The first step in this process involves calculating the number of valence electrons in the molecule or ion. For a neutral molecule this is nothing more than the sum of the valence electrons on each atom.

The Table is set up so as to indicate the number of electron shells in each atom and the number of valence electrons (electrons in the outermost shell) in the atom. As you descend rows in the Table, the number of electron shells in the atom increases.

Print Earth Lab: Valence Electrons ... 1 Just when you thought electrons were electrons, along comes valence electrons. Valence electrons are the outermost electrons in an atom's electron cloud. These electrons determine the chemical properties of an element.

The first step involves calculating the number of valence electrons in the molecule or ion. For a neutral molecule it is the sum of the valence electrons of each atom. If the molecule carries an electric charge, we add one electron for each negative charge or subtract one electron for each positive charge.

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.
