[00:00:00]are they experiment rather for gates than other for satanic model rather than another for scientific model according to another for a God according to another for the nucleus plays the role of the Sun the nucleus plays the role of the Sun and the electrons revolve around the nucleus and the electrons revolve around the nucleus just like the planets in the solar system and the electrons revolve around the nucleus just like the planets in the solar system again I eat according to rather for nucleus plays the role of a Sun this a nucleus which plays a role of the Sun which is positively charged I've already said you brother for discovered nucleus and electrons are revolving around the nucleus in their own part in the circular path you can see the circular path all right electrons revolving at the nucleus in circular path all right just like a planets in the solar system so he said that just as the planets is moving in the solar system around the Sun similarly electrons is moving around the nucleus all right so he compared his atomic model to the planetary motion of the Sun began Silla or at he compared his atomic model to the planetary motion of the Sun he compared his atomic model all right ok not so he said that why he left ox is not merging into the nucleus because nucleus is possibly charged so definitely the nucleus is pulling data transfers itself which is negatively charged so definitely lectrons should merge into the nucleus the bands are given by he must add the just like plan X is not falling into the Sun discipline it which is moving in its orbit is falling into the Sun why because it is guided by centripetal force and centrifugal force so that force is the same thing that the centripetal force which is applied by the electrons or the this nucleus is not allowing the electrons to fall into the nucleus the centripetal force with the presence of the centripetal force which is present on it in the planets and the Sun we can say that centripetal and the centrifugal force which balances each other due to which the planets which is moving in their own path is just moving their own orbit and they don't fall into the Sun similarly here also the same thing it happens just given by another so hence according to Rutherford an atom has got two parts all right Anna's got two part one is the nucleus which consists of the neutrons and the products now of course the neutrons has been discovered for that reason we given a nucleus and the electrons is moving around the nucleus in an extra nuclear part in the circular path we can say the electrons are moving understood already set according to another four we are having the nucleus which is possibly charged with the densest but I can say the nucleus is and it's very small in size already a city the size of the nucleus is 10 to the power minus 13 centimeter compared to that of an atom which is 10 to the power minus 8 centimeter and just now I said you where the size of the nucleus was actually there for another for gave a very interesting answer he said that the nucleus is nothing but a cricket ball and the atom is like a cricket field which is a 5 kilometer radius so anywhere you keep the cricket ball in that particular 5 cubic lattice cricket field you cannot find it out why because the cricket ball is very very very very small compared to that 500's cricket field here also same thing the nucleus is very - very tennis because the entire mass of the nucleus is concentrated here in turn odds of the nucleus he said and the electrons are moving and the nucleus has circular path and this path this one he said as an extra nuclear part in circular path electron is moving and is managed by the centripetal force due to which it is balances where the centripetal force which is not falling into the nucleus or if the electrons is not being what you can say attracted the nucleus and it is not falling into the nucleus what it is not merging into the nucleus because of that Clara so this was basically the picture given by another code we can see fine now we will come to the drawbacks of the brother force atomic model not it because I study the constant student girls other for another course or it was neil board so before going to the Neil Bohr's atomic model another force atomic model was challenged by Maxwell listen carefully Maxwell says that that any charged particle moving in a circular path any charged particle when it is moving in a circular path it is liable to release energy all right it's liable to release energy because what do you find is that this is an igneous isn't it the electrons is moving in a circular path in this with electron is go in a circular path clear the electron is moving this is electron which is moving in a circular path so what we said that when this electrons is move in a circular path because circular path is not made up of cement and bricks it's not a concrete path what is that it's an energy level so Maxwell said correctly said that see when an electron is moving well in any object is moving in a circular path object it's not neutral charge particle remember that charge particle not I'm not talking about neutral particle because he said that what Rutherford said he said that electrons plays the role of the planets and the nucleus plays the role of the Sun he can say that he said that we cannot compare very clever why because some planets they are the macroscopic objects and they neutral in nature but nucleus electrons their microscopic object my nude objects and they are charged they are not neutral so we cannot compare it first of all no comparison is there understood now they are microscopic and they are neutral Sun more art and all things planets and the sound but here the electron is a charged particle and nucleus is a charged one and it is microscopic in nature so there is no comparison first of all we cannot compare it the way which has been said by another for the definition which was good to another for about his atomic model we cannot do so why he gave decent guided that's the reason I'm saying you that if a charged particle is moving in a circular path if it is moving in a circular path it is laboratories energy because we will study this in higher class that when a charged particle is flowing let us say this is a part and this a charged particle is there when it is moving for each and every moment there is a change in angular velocity there is a change in angular velocity one velocity is a linear velocity another is an angular velocity because I am is changing every moment my angle is changing this is change in angular velocity due to change in angular velocity what you find is that this is changing energy because angular velocity is related to energy like a kinetic energy half MV square that is a linear velocity here same thing we are also having the angular velocity which will give you that energy now what you find is that as angular velocity is changing twenty ways it is decreasing very simply because an electron when a charged particle is moving in a circular path it is losing its energy is losing every kinetics losing its energy because every moment that actually it's decreasing well also resorting to these in this decreasing and due to which what it happens is that it loses energy and do this loss in energy I said already this part is made up of energy but it's as the Energy's being lost the path gets shorter and shorter shorter and shorter it becomes smaller and smaller as you can see time to run drawn it clearer it becomes smaller and smaller say leptons is moving the path gets shorter and shorter shorter and shorter ultimately it comes closer to the nucleus or it ultimately it comes closer to the nucleus and hence it gets it it will fall into the nucleus if an electron is moving in a circular path as it was suggested by Rutherford it will fall into the nucleus and it will get destroyed to happen this snob I told a long time to you but to happen this for the electron the time taken which was calculated with Maxwell to be as 10 to the power minus 8 second it takes for one electron to fall into the nucleus and get destroyed it takes 10 to the power minus 8 second Maxwell's are hydrated then suppose let us compare what other four said is correct that electrons plays the role of the plant and this nucleus plays the role of a Sun that means let us consider that whatever the electrons is present in our planet Earth all right what are the electrons is being present in our planet has some trillions of electrons are being present in our planet Earth so this electrons is also going to second so it may happen that the electron will fall into the nucleus as it'll service it to such a state no max it will form the nucleus and get destroyed so if one electron is taking 10 to the power minus X again it will take few hours for that to be get destroyed because it will fall into destroy destroy gear Maxwell said that suppose let us consider one another for sadists correct so artists consisting of electrons are not our you know income their heart consists of charge particle in transition system so you get once is going the same way particle your trance is moving just serve the panics and so last time you said that electrons are going so when this are this consists of this particular charged particle that is electrons which is moving so this also moving and the Sun electrons is moving that is going to the cons are moving so hence what can happen is that as he calculated and said to destroy one electron 10 to the power minus 8 seconds are there so what consists some some trillions of electrons are there if you calculate the time taken is few hours for the arts to fall into the Sun and get destroyed did hurt this time now he told this one in summers sixteenth or seventeenth century but it still today we are there that means for it was suggested that other foot is not correct it was wrong which was suggesting another fourth and electrons is going in a circular path because any charged particle if it is moving in a circular path then this library to release energy to lose energy typically it will fall into the nucleus and get destroyed all right so Hennessey said that we cannot compare the atomic model suggested with other for to the planetary motion we cannot compare it it is not at all comparable microscopic neutral particle but here this is microscopic uncharged particles it is not comparable he said also that if at all be compared then the art will in der stadt suppose we consider the artists and the charged particle so it consists of electrons and hence the electrons is the nucleus and understand it will take you all for that to describe so it is not possible because it was said in some 16th or 17th century in the late sixteen or the beginning of 17th century it is being said so it's not possible the still today we are living listening so hence it was me disheartened in that event maxvill all right so this was the drawback of the other four SATA McMorris ultimately what we can thank you brotherhood could not also say anything about that stability of an actor ultimately could not sleep and one cleric goes to other foot for the discovery of nucleus that is a credit which goes to the other foot there an atom consists of positively charged particle nucleus which is having very high density because an entire mass of an atom is concentrated inside a nucleus which consists of neutrons or protons because electrons is moving in a path but it of course it is moving in a path electrons is moving clear in circular path is a distance is resisted by mother for all right okay and the electrons what I find is that as it is moving in circular paths and the charge of mass of the nuclear electrons is quite negligible compared to that of the neutrons and protons understood the rather force are you being modern and the drawbacks also thank you very much
