Web determine the element’s number of valence electrons (# of electrons in the “outermost” shell).
Each element in a group has the same number of electrons in their outer energy level (the valence level). Magnetic properties of complex ions. The number of valence electrons determines most of an atom's chemical behaviors. Sum up the total number of valence electrons for the elements in the molecule.
Magnetic properties of complex ions: If the molecule is charged, subtract one electron for each positive charge or add one electron for each negative charge. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.
