the element phosphorus
3
Boron family is group IIIA so 3 electrons are in the outermost shell.
Boron has 3 valence electrons.Boron has 3 valence electrons.
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
They will gain 3 electrons from something with 3 valence electrons.

Atomic no. of nitrogen is 7 The valence electrons outside are 5 VALENCY= 8-5=3
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.

3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
