How many valence electrons does #N# have?

Answer 1

Nitrogen have 5 valence electrons.

Nitrogen atomic number (see Periodic Table, for example: https://tutor.hix.ai) is #Z = 7#. Then, the electronic structure of nitrogen is: #1 s^2 2 s^2 2 p^3#. Valence electrons are the electrons an atom have in the last level. In the nitrogen, last level is level 2, then there are 5 electrons of valence.
