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.
Zinc is a metal. It is called an âessential trace elementâ because very small amounts of zinc are necessary for human health. Zinc is used for treatment and prevention of zinc deficiency and its consequences, including stunted growth and acute diarrhea in children, and slow wound healing.t is called an âessential trace elementâ because very small amounts of zinc are necessary for human health.
