What is the mass number of sulfur? What is the mass number of a neutron? How many iron atoms are there in 0.32 mol of Fe2O3? What element has a mass number of 4? What is the mass number of arsenic? What is the mass number of nickel? What is curium's atomic mass number? What...
number of −2 because it can donate two electrons. In an electronically neutral substance, the sum of the oxidation numbers is zero; for example, inhematite(Fe2O3) the oxidation number of the two iron atoms (+6 in total) balances the oxidation number of the three oxygen atoms (−6)...
