A. They belong to group IA
B. They are stable with 3 or 4 electrons
C. They are stable with 2 electrons only
D. They do not have 8 electrons in their outermost shells

 

Good Day

Problem:

The ions Li+, Be2+ and H- do not follow the octet rule. Why?

Answer:

C. They are stable with 2 electrons only

Some definition of the octet rules states that atoms would like to have 8 electrons in its valence shell. However, there are atoms which only have the first shell which can only hold 2 electrons on it like ions Li+, Be2+ and H-.

Which is said to be exemption to the rule.

Hope it helps...=)
