WHY THE M SHELLS IS CAN ACCOMMODATE 18 ELECTRONS BUT IT DOSE'NT CONSTITUTE MORE THAN 8 ELECTRONS FOR ELEMENTS HAVING ATOMIC NUMBER MORE THAN 18?

Open in App

Solution

The solution is as follows:

1. According to Bohr's rule:

There cannot be more than 8 electrons in the anti-valence shell of any atom.

2. Thus, if have to fill 18 electrons in an atom, electronic configuration is as follows:

2,8,8
