The structure of nitrogen atoms and molecules.

The chemical element nitrogen (N) has serial number 7, which means that its nucleus contains 7 protons, and 7 electrons revolve around it. The relative atomic mass of nitrogen is -14, which means that in addition to protons, there are 7 neutrons in the nucleus. OH is in the second period, which means that the electrons rotate at two energy levels, this is an element of the 5th group of the main subgroup – at the last energy level it has 5 electrons.
Atomic structure 1s2 2s2 2p3. The nitrogen molecule consists of two atoms – N2.
