The name "valence electrons" obviously comes from the older idea of valences; the mysterious numbers Mendeleev used can now be explained via electron configurations. Look again at the applet and the valence chart below, and see if you can tell why the valence system worked and what the numbers really mean.

Valence electrons have the ability, like electrons in inner shells, to absorb or release energy in the form of photons. This gain or loss of energy can trigger an electron to move (jump) to another shell or even break free from the atom and its valence shell.
