The number of valence electrons in any element can be found from the element's group number on the Periodic Table. Phosphorus has a group number of 5 (15 in some periodic tables, in which case the valence is the group number minus ten). Thus, phosphorus has 5 valence electrons.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
Zinc has two valence electrons.
Aluminum has 3 valence electrons.
5 valence electrons.
