[00:00:02]Hello.

[00:00:10]Hello. Good evening.

[00:00:24]>> Hello. Hello. Hello.

[00:00:27]>> Hello.

[00:00:29]Okay.

[00:00:36]Hello everyone.

[00:00:38]Good evening and welcome back to a new live of Janom.

[00:00:50]Good evening.

[00:01:07]YouTube platform. Okay.

[00:01:22]faculty first year or fourth chapter that is chemical bonding and molecular structure important chapter Chemistry.

[00:01:36]Chapter Brych.

[00:02:04]Chapter 1. Chapter 2, Chapter 3. Chapter Minimum half century. Okay. So, minimum half century to.

[00:02:31]So already chapter But we need to completely discuss completely discuss Okay.

[00:04:05]Okay.

[00:04:19]Yes.

[00:04:30]Okay.

[00:04:33]Inorganceptryceptience.

[00:04:45]Fore concept. Okay.

[00:05:21]for start.

[00:05:50]Yes.

[00:05:55]Mhm.

[00:05:59]Okay.

[00:06:09]for chemistry, physics, math, biology.

[00:06:33]December.

[00:06:51]Okay.

[00:06:53]So, oh minute, take minute.

[00:07:12]Okay, just minute.

[00:07:31]Oh sir.

[00:07:34]Okay.

[00:07:40]I promise. Okay.

[00:07:53]Physics, chemistry, math, biology, 11 WhatsApp WhatsApp.

[00:08:44]Okay. Then for chemistry, physics, maths, biology.

[00:09:15]Then Okay.

[00:10:09]So, Fore system.

[00:10:42]Solar for system.

[00:11:22]Highway foreign.

[00:11:40]So imaginary part.

[00:11:52]Fore! Foreign! Foreign!

[00:12:02]Fore force forcem force force The chemical force which keeps the atoms in a molecule together is called a chemical bond. actually.

[00:13:11]Okay. Okay.

[00:13:15]First partap.

[00:13:19]Okay.

[00:13:23]Okay.

[00:13:26]Okay. So force single.

[00:13:51]Okay. So, approach to chemical bonding.

[00:14:16]Now that atoms achieve the stable octed when they are linked by chemical bonds. Soon oct. for example.

[00:15:41]Ultimately, Neon argon gas. Okay.

[00:16:20]Noble gas. Achieve concept. related.

[00:17:05]Max outermost cell.

[00:17:18]Outer Most Valenc outer cell directly. Octately India levelour.

[00:19:39]Noble gas to electronic configuration.

[00:19:42]Noble gas. That means Lithium.

[00:20:09]Maxium.

[00:20:29]foreign atomic number two.

[00:20:59]configuration.

[00:21:00]So ultimately configuration 2.

[00:21:07]So that means oxygen number 2.

[00:21:36]for Neon configuration.

[00:22:15]Soon carbon dioxide.

[00:22:27]So carbon dioxide.

[00:22:42]Oxygen 2.

[00:23:22]Directly oxygen.

[00:23:45]So oxygen Okay.

[00:24:05]oxygen configuration 26 oxygen.

[00:24:59]So first observation valance electance L2 81 281qua carbon dioxide. Chapter number four, class.

[00:26:12]Sodium.

[00:26:26]In fact, one chapter 2. Chapter 3.

[00:26:29]Chapter four.

[00:26:31]Very basic chapters of chemistry.

[00:26:42]Okay.

[00:26:50]I am from Bangladesh.

[00:26:54]Okay.

[00:26:56]for Okay, that's a mistake actually.

[00:27:19]Very good. Very good. Very good. Very good.

[00:27:22]Very good.

[00:27:26]26.

[00:27:36]Yes.

[00:27:50]Sodium or atomic number 11. So, sodium gasification.

[00:28:08]So, electig.

[00:28:26]Okay. So, chlorine configuration 287 287 atomic number 17. So chlorine or nearest noble gasine number 18 number electine So Ionic complete octed. foreign.

[00:29:45]Okay.

[00:30:04]Okay.

[00:30:38]So only the valence electron.

[00:30:45]electron power.

[00:31:12]Power.

[00:31:31]So, so many technical things are related to our classes. That's why sometimes we face these difficulties.

[00:31:56]Okay.

[00:32:13]Start only.

[00:32:28]Okay.

[00:32:32]Okay.

[00:32:54]Sorry for the inconvenience.

[00:33:05]Wait, wait.

[00:33:33]connection.

[00:33:40]Wait.

[00:33:54]Okay.

[00:33:56]So for bone form only chlorine chlorine elect 28.

[00:34:33]So electrons involve involve A287 number.

[00:35:15]So outermost electron involve Okay.

[00:35:37]Only valence electron that means outermost electron only outermost electrons represent.

[00:35:51]Yes.

[00:35:54]head.

[00:35:56]Okay. So only electing valency valenc very much related to this.

[00:36:53]So valated directly related to bone form.

[00:37:12]Be careful.

[00:37:13]Be careful. Okay.

[00:37:25]You have to complete outermost electron. So observation symbol for the elements.

[00:38:20]281. That means Magnesium atomic number 12. Electronic configuration 82 that means magnesium.

[00:38:59]So it is very simple. Okay.

[00:39:33]Simple thing. It's a very simple thing.

[00:39:38]foreign.

[00:39:50]So that's why oxygen oxygen starts out. Okay. Oxygen starts out.

[00:40:29]Okay.

[00:40:40]Clear. Okay.

[00:40:46]Next. Formation of ions. Formation of element.

[00:41:24]Okay. Electropositive.

[00:41:37]So highly electro negative electro negative electropositive elective.

[00:42:32]elective connective elective or electro negative.

[00:43:06]nonmetallic.

[00:43:25]These are some AI generated diagrams.

[00:43:33]Okay.

[00:43:44]configuration.

[00:43:51]So 28 sorry negative. So negative 10 11.

[00:44:29]So + 11us 10 ultimately plus one. So Lose chemical reaction.

[00:45:15]always.

[00:45:32]Okay.

[00:45:42]configuration number 28. So chlorine electig So 8 electronification elect 17.

[00:46:28]So plus 17 + 17 - 17 ultimately zero.

[00:46:38]So minus 11 negative metallic spaces nonmetallic spaces that means electro and electro negative.

[00:46:59]Connectiglas configuration stable.

[00:47:34]negative.

[00:47:46]YouTube Manu set everything fine.

[00:48:16]Fine.

[00:48:19]Okay. Okay.

[00:48:25]Clear.

[00:48:36]Clear.

[00:48:37]So ultimately for electronic configuration forion.

[00:49:15]Then always say element exceptional.

[00:49:46]Hydrogen configuration only one of the elements.

[00:50:15]to nearest configuration. So ultimately lithium berilium boron.

[00:50:48]Lithium berilium boron. Boron hydrogen element.

[00:51:06]During chemical reaction reaction atoms tend to adjust their electrment.

[00:51:14]electr Most rule configuration octed.

[00:51:59]So that is called rule. Ultimately that is called octet rule. Clear? Octetle easily.

[00:52:21]easily Then nitrogen or 2a 5 that means nitrogen.

[00:52:48]So nitrogen nitrogen or valency nitrogen or valency. So magnesium magnesium 22 magnesium number electig 2.

[00:53:31]So 28 It's like that only.

[00:54:23]So valency valency.

[00:54:45]8 minus valence electable.

[00:55:01]foreign.

[00:55:32]8us valence electron 8us valence electchech foreign.

[00:56:01]Okay.

[00:56:15]NC text.

[00:56:41]Okay. So nextal It is just a symbolic representation.

[00:57:46]Okay.

[00:58:01]nonmetal.

[00:58:05]So, So yes, valency hole four.

[00:58:44]Carbon or valency four contribution chlorin.

[00:59:31]So bone concept.

[01:00:11]Happy.

[01:00:30]So for clear bone formalent bone form in between nonmetals single single single bone. Single bone.

[01:01:22]Single bone.

[01:01:34]Double coalent bond.

[01:01:48]So oxygen oxygen oxygen oxygen.

[01:02:44]So, oxygen.

[01:02:58]Okay. So, Double double coalent.

[01:03:39]For example, Nitrogen. Nitrogen for example. So nitrogen configuration nitrogen configuration 2.

[01:03:55]So nitrogenit.

[01:04:11]Okay. So nitrogen symbol visible.

[01:04:37]Okay.

[01:05:02]pair of electron.

[01:05:08]It is a very simple thing.

[01:05:26]pairs of electron. Clear. Clear. Up to this point.

[01:05:33]Up to this point. Clear.

[01:05:40]Care is Okay, very good.

[01:06:27]Okay, clear.

[01:06:33]So next topic dot structure dot structure. Okay.

[01:06:53]Okay.

[01:07:02]Okay.

[01:07:05]Which molecule has example CO3 2 negative. Okay.

[01:07:47]CO3 to negative.

[01:07:53]So first of all first of all count the total number of valence electrons. So number of valence electrons number of valence.

[01:08:20]Okay.

[01:08:26]So electron 24. Okay. Then next arrange the Arrange the surrounding atoms around the around the central atom.

[01:09:21]lowgity.

[01:09:26]Generally the low generally the lower electro negatives atom is considered.

[01:09:52]Atom is considered as central atom.

[01:10:10]So Second step.

[01:10:43]Just like you don't need to describe these steps.

[01:10:52]Okay.

[01:10:54]Number two.

[01:10:56]Number two.

[01:11:08]Except hydrogen.

[01:11:22]electro negativity carbon oxygen or electro negativity.

[01:11:36]Okay.

[01:11:42]H.

[01:12:11]Okay.

[01:12:16]Okay.

[01:12:19]Okay.

[01:12:27]surrounding connect the atoms with single bonds.

[01:12:52]So 24 already.

[01:13:07]Okay.

[01:13:10]Next number four.

[01:13:15]Complete the octate.

[01:13:17]Complete the octed.

[01:13:23]of the surrounding following surrounding atoms.

[01:13:38]Complete the octate of the surrounding atoms. Surrounding.

[01:13:51]1 2 3 4 5 6 24 surroundings.

[01:14:25]Complete the octed.

[01:14:29]Complete the octed of the central atom.

[01:14:52]elected.

[01:15:22]to complete. Okay.

[01:15:46]complete.

[01:15:47]Yes.

[01:16:02]for bisha bj.

[01:16:43]to complete.

[01:16:50]for nextally.

[01:17:10]Soon.

[01:17:35]Okay.

[01:17:38]Then Elect.

[01:18:18]So oxygen overall.

[01:18:50]CO3 2 negative CO3 2 negative. Okay.

[01:19:14]Clear.

[01:19:19]Okay.

[01:19:35]bad.

[01:19:37]Okay. So, next HNO3 related to HNO3.

[01:20:02]Okay. H3 oxygen. So again 24 electron 24 arrange the surrounding atom around the central atom.

[01:20:57]that is not possible. So second generally lowerity So nitrogen surrounding very important important important concept you need to understand it. Okay? Otherwise for this one is the formula of nitric acid.

[01:22:25]Nitric acid or formula nitric acid strong posit.

[01:22:49]So hydrogen oxygen is more electrogative than nitrogen.

[01:23:22]Hit you need to understand this concept also.

[01:23:45]Okay.

[01:23:48]Clear.

[01:23:58]already.

[01:24:10]foreign.

[01:24:38]Complete.

[01:24:40]Central elect.

[01:25:08]So oxygen or nitrogen.

[01:25:20]So no problem.

[01:25:38]Yes. So STS are to complete struct.

[01:25:47]Okay.

[01:26:13]oxygen.

[01:26:38]Negative. Negative. Positive. So negative charge structure of HN. NO3 or nitric acid clear.

[01:27:24]Okay. So main concept of course battery.

[01:28:13]You can ignore my talk. Okay.

[01:28:42]That is not possible for us. In fact, it is not possible possible for you to not possible. So, but still, for next important topic. I hope Okay.

[01:30:18]If you want that is okay. No problem.

[01:30:40]What about Okay from Camita from Cam.

[01:30:51]Lokma Hussein from Borpeta.

[01:30:54]Rahman from Roy from Dubir.

[01:31:01]Procas from Gulagatan proc from Gulagat.

[01:31:08]Aru nila or Jun from Migo. Are% literally why I remember his name and address also.

[01:31:55]So, okay.

[01:32:04]So, Chapter completely live.

[01:32:42]Okay. Kashmir.

[01:32:45]Wow.
