0 in the elemental form
The oxidation number of hafnium (Hf) typically ranges from +2 to +4 in its compounds.
Hafnium typically forms a +4 oxidation state in its compounds, resulting in the formation of Hf^4+ ions. These ions have a charge of +4 and are commonly found in hafnium compounds.

The atomic number of hafnium (Hf) is 72.The atomic weight of Hf is 178.49 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
stop worrying about it .........
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
The atomic number of hafnium is 72. So there is 72 protons.
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Position of hafnium in the periodic table: group 4, period 6, atomic number 72.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
