4.1 Writing and Balancing Chemical Equations – Chemistry
The nuers of H atoms on the reactant and product sides of the equation are equal, but the nuers of O atoms are not. To achieve balance, the coefficients of the equation may be changed as needed. Keep in mind, of course, that the formula subscripts define, in part, the identity of the substance, and so these cannot be changed without altering the qualitative meaning of the equation.

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.
