The Parts of the Periodic Table - Angelo

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.
