Oxidation States 12 of 14 > Neutral compounds In a neutral compound, the sum of the oxidation states is zero. Note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. In H20, for example, each hydrogen atom has an oxidation state of +1 and each oxygen atom has an oxidation state of -2 for a total nstant Oxidation states are important for keeping track of electrons in oxidation-reduction reactions....

Electron Configurations of lons ③ 19 01 23 Review Constants Periodic Table When an atom forms an ion, it will gain or lose electrons to attain a more stable electron configuration, frequently that of a noblo gas. Nonmetals tend to form anions by gaining electrons, which enter the lowest energy unoccupied orbital. Metais tend to form cations by losing electrons. Main group motals lose electrons in the reverso order of filling. Transition metals, however, lose s electrons first. Part A...
