Oxygen belongs to the chalcogen family, which is a group of nonmetals on the periodic table known for their chemical properties like forming compounds with metals.
Oxygen typically has a charge of -2 when it forms compounds.
The formula without the coefficient has 2 oxygens, but multiply that by the coefficient of 6 gets you 12 oxygens. In chemistry, a coefficient in front of a compound applies to everything in that compound even though there aren't any parentheses.
The S is the symbol for sulfur, and the O represents oxygen; because the 2 comes after the O we know there are two oxygens to every sulfur. So the compound is sulfur dioxide. Di- means two, so this is sulfur with two oxygens.
molecular weight of NiSO4.7H2O is 1101.3 and it has 11 oxygens. So percentage of oxygen = (7 x 16) / 1101.3 = 112 / 1101.3 = 0.102 or 10.2%
Oxygen typically has a charge of -2 when it forms compounds.
