It tells you how much of a molecule is made up of each element. - APEX

mol/l

only compounds with the (aq) state symbol

if oxidation states change, it is a redox reaction

Combines with oxygen

The reactant that has the atom that gets oxidized

An element gains one or more electrons

In an atom of an element has one or two valence electrons and is not a helium atom, the most likely oxidation state is positive by the number of valence electrons, while if the atom of an element has seven or six electrons, the most likely oxidation state is negative by the number of electrons required to total eight valence electrons. Helium and all the atoms with eight valence electrons have a most likely oxidation state of zero, corresponding to no reaction.
