Question

Q.2 Give reasons for the following:
To attain stable electronic configuration of the nearest noble gas
1. Hydrogen atom 1 H - needs one electron .
2. Oxygen atom 16,0 - needs two electrons.
3. Nitrogen atom 14-N - needs three electrons.
4. Carbon atom 126C - needs four electrons.
5. Chlorine atom 3517C1 - needs one electron.

Answer 1

Explanation:

1. bcs in the 1st class it has 2 electrons so it requires only one more electron to become stable.

2.bcs the electronic configuration is 2, 8, 6 and in the third shell it has 8 electrons so we need two more electrons to make it stable.

3. as for N it is 2,8,4 and as it will share the electrons so it requires only three.
