Ease of oxidation is how easily it loses electrons. Electrons are the basis of chemical reactions. If chemical A is more easily oxidized than B, then B is a relative oxidizer to A, so in terms of the activity series, the elements that are more easily oxidized can react with more chemicals, since they will be able to act as reducing agents to more chemicals.
