The last letter represents how many valence electrons are. So:

K: 2e

L: 8e

M: 5e

The valence of the element is 3 (8-no. of valence electrons). Note that that formula is correct for nonmetals only. The element is P and has the electronic configuration [Ne]3s2 3p3 or 1s2 2s2 2p6 3s2 3p3. It has to gain 3e to get from 3p3 to 3p6.

How can the number of valence electrons be determined from the periodic table?

By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
