4
9
10
16
32

Answer 1

FULL ANSWER
There are six electron shells, and these have the following letter classifications: K, L, M, N, O and P. The electron capacity for each shell is as follows: K=2, L=8, M=18, N=32, O=50 and P=72. An electron shell at one of the six energy levels does not have to be full before electrons start occupying the next level. The Periodic Table details the electron configuration for elements.

Answer 2

guess .....
translating money into cash ... 32 the N shell ? and where that is in the P table I've no idea 'cos I've not got one in front of me
