Verified step by step guidance1
Identify the group number of the nitrogen group in the periodic table, which is Group 15.
Recall that the group number for main group elements corresponds to the number of valence electrons for those elements.
Understand that elements in Group 15 have 5 valence electrons because the group number minus 10 gives the valence electrons for groups 13 to 18 (i.e., 15 - 10 = 5).
Recognize that valence electrons are the electrons in the outermost shell of an atom and determine the chemical properties and bonding behavior of the element.
Conclude that all elements in the nitrogen group (Group 15) have 5 valence electrons.
