Question

The bohr's formula shows that the third shell should have 18 ELECTRONS whereas it is 2,8,8,18 why is it so???

Solution

Basically, there are 18 because each shell is divided into s, p and d sub-shells. s always holds 2, p always holds 6 and d always holds 6 (there's an f shell that holds 14, it goes up in 4's xD)

Basically, shell 3, when full, looks like this:

1s2, 2s2, 2p6, 3s2, 3p6, 3d10

There are 2 on the 1st shell, 2+6=8 on the 2nd shell, and 2+6+10=18 on the 3rd shell
