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?
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
