Free valence electrons
WebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. … Learn for free about math, art, computer programming, economics, physics, … The simplest being the first period elements (hydrogen and helium).
