2026 GCE Science Paper 2 Predicted | Exam Type of Questions

[00:00:00]Hello, welcome.

[00:00:02]In today's lesson, we have a long teacher teacher.

[00:00:07]It is a risky to go like your science paper two without knowing such type of questions.

[00:00:15]These are the exam format type of question that that comes in science paper two.

[00:00:20]Let us look at this question. It was saying figure 4.1 shows an electronic structure for element Q.

[00:00:32]So now, it it said the name element Q.

[00:00:36]So for you to name element Q, you need just to to count the number of electron it has. You see 1 2 3 4 5 6 7 8 9 10. Then when you count this one in the last show, it has got seven. All together it has got 17. So when you go on the periodic table, you are going to find the number which has got 17 down is chlorine. So here we are going to say the name of the element Q is chlorine.

[00:01:07]Soon, we are done with this one. So second equation, it was saying state the period of the periodic table where element Q belongs.

[00:01:17]Explain your answer. So for you to to know the period where it belongs, you need just to count the number of shows. You see 1 2 3. So it is in you see period D three because because there are are three electron shows.

[00:01:53]If you want you can even say Uh, because it it has got three electron shells, group number is always equal to the number of Uh, or she period number is always equal to the number of shells an element has.

[00:02:10]So, now Then, the The next question was saying, "Explain how an atom of element Q acquire chemical stability."

[00:02:25]How does it come acquire How does it become stable?

[00:02:30]You say You You say by gaining by gaining one electron in the outer most shell.

[00:03:02]So, what you need to understand nonmetals, they gain electrons for them to become stable. Like metals, they start from group one to group three.

[00:03:11]Group number is always equal to the number of electron in the outermost shell. So, like all metals, if it is in group one, it will lose one electron for it to become stable. Group two, it will lose two electrons for it to become stable. Group three, it will lose three electrons for it to become stable. But, for this one, if it Nonmetals, they don't lose electron. For it to have 80 electron in the last shell, it needs to gain one electron.

[00:03:38]So, now, the last question was saying, "Explain what you understand by the term nuclear number." So, nuclear number is the total You say total number of proton and the neutrons present in the nucleus of nucleus of an atom.

[00:04:26]That's all. So, don't forget to subscribe for more exam preparation and prediction exam question.
