Want this question answered?
In group 3A elements, or elements in group 13, have only one unpaired electrons.
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
The group 16 elements have 6 valence electrons. However, they generally only have two unpaired electrons available for bonding.
Any group 5 element
Group 2A elements tend to GAIN electrons!!

2 unpaired valence electrons in their elemental state.
Everything in the group 1 of periodic table
The elements in group 15 Nitrogen, N; Phosphorus, P; Arsenic, As; Antimony, Sb and Bismuth, Bi all have a ground state with 3 unpaired electrons in p orbitals.
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Any group 5 element
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
All elements in the same A group will have the same number of valence electrons.

Like all the elements in the nitrogen family, Arsenic has 5 valence electrons. The five electrons inhabit the 4s and 4p orbitals: As: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3
