Describe the structure of the atom N (the number of protons, electrons, neutrons, the distribution of electrons in the atom).

Chemical element – nitrogen (N)
Is in the second period (small), in the fifth group (main subgroup)
Sequential number – 7
The relative atomic mass is 14
Atom structure:
The number of electrons is 7, the number of protons is 7, in order to calculate the number of neutrons, it is necessary to subtract the ordinal number from the relative atomic mass, we get: 14 – 7 = 7
+ 7N) 2) 5 1s2 2s2 2p3
At the last energy level there are 3 electrons, the level is not complete.
The highest valency is V
Superior oxide formula: N2O5, the character of the oxide is acidic.
Acid formula: HNO3
Volatile hydrogen compound: NH3
