Ryder Leon · Answer 1

The answer should be A, Valence Electrons!

Marlon Oneill · Answer 2

Answer: A) valence electrons

Explanation:

The elements in the periodic table are arranged in order of increasing atomic numbers. The horizontal rows are called as periods and vertical columns are called as groups.

The elements in the groups are arranged in order of increasing atomic numbers and thus contain different number of protons and different number of neutrons. the electrons are added to new energy shells but contain same valence electrons and thus have similar chemical reactivity.

Group 15 elements are called as nitrogen family as the first element id nitrogen.
