There is no oxidation number, nor are there common oxidation states for helium, so 0.
Helium does not form any known stable compounds, and thus it is nearly always in the 0 oxidation state.
Zero. Elemnts always have a zero oxidation state hoever they are bonded. Helium is a noble gas, monoatomic and forms no compounds so as it happens it is always zero.
No as it doesn't as it doesn't form compounds. The only possible oxidation number is zero for elemental helium
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
Zinc is in oxidation state +2 and oxygen in oxidation state -2. Zinc Oxide itself has not net charge/oxidation state.
0 oxidation state
Most common oxidation state of Helium is 0, in which it is in elementary and unreacted form
Helium does not form any known stable compounds, and thus it is nearly always in the 0 oxidation state.
Helium do not form ions.It has only zero Oxidation number.
Zero. Elemnts always have a zero oxidation state hoever they are bonded. Helium is a noble gas, monoatomic and forms no compounds so as it happens it is always zero.
No as it doesn't as it doesn't form compounds. The only possible oxidation number is zero for elemental helium
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The oxidation state of calcium is +2.
The oxidation state of carbon in methanol (CH3OH) is +2. This is because oxygen has an oxidation state of -2 and hydrogen has an oxidation state of +1, so the carbon must have an oxidation state of +2 to balance the charges in the molecule.
2 oxidation state
O = -2 oxidation state H = +1 oxidation state
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
