Answer 2

The number of valence electrons present in nitrogen is 3.  

• Nitrogen is a gas present in the atmosphere in most abundance.  The symbol of this element is 'N' which has atomic number 7 and atomic mass 14.
• This means that nitrogen includes 7 protons, 7 electrons and 7 neutrons, and makes up 14 sub-atomic particles in the nucleus of the atom (protons + neutrons).
• Nitrogen is found to have either 5 valence electrons in its outermost shell and has a valency of -3.
• The configuration of nitrogen is [He] $2s^2 2p^3$ which concludes that the electrons present in the outer orbital are 5, and it can gain 3 electrons to become stable.
