-'''Electropositivity''' is a measure of an element's ability to donate [[electrons]], and therefore form positive [[ions]]. Mainly, this is an attribute of [[metals]], meaning that for the most part, the greater the metallic character of an [[chemical element|element]], the greater the electropositivity. Therfore the [[alkali metals]] are most electropositive of all.This is because they have a single electron in their outer shell and, as this is relatively far from the nucleus of the atom, it is easily lost; in other words, these metals have low [[ionization energies.]][Electropositivity," Microsoft® Encarta® Online Encyclopedia 2009

-Electropositivity is opposed to [[electronegativity]]: the ability of an element to attract electrons. While electronegativity increases along [[Period (periodic table)|periods]] in the [[periodic table]], and decreases down [[Periodic table group|groups]], electropositivity ''decreases'' along periods and ''increases'' down groups.

-[[Electropositive metal]]s are also utilized as shark repellents, since they generate measurable voltages in a seawater electrolyte relative to a shark.
