Helium do not form ions.It has only zero Oxidation number.
No as it doesn't as it doesn't form compounds. The only possible oxidation number is zero for elemental helium
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.
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.
Most common oxidation state of Helium is 0, in which it is in elementary and unreacted form
oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Zn has oxidation number +2; S has oxidation number -2
The oxidation number for H is +1, and the oxidation number for O is -1.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
Oxidation number of Si is +4.Oxidation number of O is -2.
