The Parts of the Periodic Table - Angelo State University

In general, metal and nonmetals coine to form ionic compounds, while nonmetals coine with other nonmetals to form covalent compounds (molecules). Since the metals are further to the left on the periodic table, they have low ionization energies and low electron affinities , so they lose electrons relatively easily and gain them with difficulty.

Oxygen, nitrogen and the rare gases

Nitrogen leaves the top of the column as a gas. Purity levels required by nitrogen users are becoming increasingly stringent and it may be liquefied again and redistilled. It is unusual for the nitrogen to have an oxygen content of more than 10 ppm and impurities contained in nitrogen for the electronics industry are measured in parts per billion.
