Answer:
The elements of group 15.
Explanation:
The elements of group 15 (column) VA of the periodic table all have electron configurations of s2p3, giving them five valence electrons. These elements include Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb) and Bismuth (Bi).
Looking at the fourth energy level or period (row) of the periodic table we will find that the element Arsenic is in the 4th energy level and in group 17. Arsenic has an electron configuration of
[Ar]4s23d104p3. The s and p orbitals of arsenic have 2 and 3 electrons respectively making 5 valence electrons.
