Question

Duplet : Helium atomic number is 2 , as there are not enough electron to follow octet rule it gains stability with 2 elections

Is this definition correct? can I use this definition for my viva?​

Answer 1

Answer:

I think this answer would be more suitable for viva

Explanation:

Helium only has 2 electrons and therefore it has a configuration of 1s2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas.

hope this helps
