5 valence electrons because it needs to gain 3 electrons in order to become stable
The valency of nitrogen is 3
Iodine has 7 valance electrons
12. Nitrogen has 5 valance e- and Oxygen has 6 valance e-. Add 1 more because it has a 1- charge.
5, it is the number of valance electrons determined by the roman numeral over the group in the periodic table of elements

Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
2 valance electrons
There are 27 valance electrons.
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
Iodine has 7 valance electrons
5 electrons
12. Nitrogen has 5 valance e- and Oxygen has 6 valance e-. Add 1 more because it has a 1- charge.
5, it is the number of valance electrons determined by the roman numeral over the group in the periodic table of elements
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
Magnesium is group II and has two valance electrons to donate to achieve the octet state. Nitrogen has 5 valance electrons so it accepts 3 into its outer shell to make an octet. So Mg3N2
