Nonmetals also have high electron affinity. This means that it is energetically favorable to add an electron to a nonmetal. So, nonmetals can be easily reduced. Metals tend to have low electron affinity so it is more difficult to add electrons (or reduce them). In short: Metals have low ionization energies and low electron affinities so they are readily oxidized. Nonmetals have high ionization energies and high electron affinities so they are readily reduced.
Nonmetals. Metalloids. Silicon for example appears lustrous, but is not malleable or ductile (it is brittle-a characteristic of some nonmetals). It is a much poorer conductor of heat and electricity than the metals. Metalloids are useful in the semiconductor industry.onmetals. Metalloids.
