Detailed explanation-1: -Nitrogen has a total of 5 valence electrons, so doubling that, we would have a total of 10 valence electrons with two nitrogen atoms.
Detailed explanation-2: -A neutral atom of nitrogen will have five valence electrons. Neutral atoms will have the same number of protons in the nucleus as they have electrons orbiting the nucleus.
Detailed explanation-3: -Why valency of nitrogen is 5? ANS: Nitrogen, which is situated at the top of Group 15 on the periodic table, has either 3 or 5 valence electrons. Because it can bond in the outer 2p and 2s orbitals, it can have 3 or 5 valence electrons.
Detailed explanation-4: -From the electronic configuration of the nitrogen atom, we come to know that the number of electrons present in the outermost shell i.e., 2rd shell is 5 electrons. Thus, the total number of valence electrons present in nitrogen atoms is five.
Detailed explanation-5: -Atoms in the nitrogen family have 5 valence electrons. They tend to share electrons when they bond. Other elements in this family are phosphorus, arsenic, antimony, and bismuth.
