Question

What is octet rule??? ​

Answer 1

Answer:

OCTET RULE :-

According to the octet rule, every atom tries to have 8 electrons in its outermost (or valence) shell or to achieve noble gas configuration . This may require them to lose, share, or gain electrons from other atoms.

For eg :-

Sodium(Na - 2, 8, 1) has 1 electron in its valence shell so it loses this 1 electron to achieve octet and to become stable.

Fluorine(F - 2, 7) has 7 electrons in its valence shell so it gains 1 electron from another atom to achieve octet and thus stability.

Nitrogen(N - 2, 5) has 5 electrons in its valence shell so it shares 3 electrons with another Nitrogen atom such that both atoms achieve octet and hence become stable.

Neon (Ne - 2, 8) has 8 electrons in its valence shell and since it has 8 electrons in its valence shell(complete octet) so it does not lose, gain or share electrons with any other atom and hence does not react and is considered "inert".

Hope this helps!

Answer 2

Answer:

˙❥The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. An exception to an octet of electrons is in the case of the first noble gas, helium, which only has two valence electrons.˙✧*。
