There is no oxidation number, nor are there common oxidation states for helium, so 0.
The oxidation state of boron is either three electrons or one electron. Boron has an valence electron configuration of ns2np1.
Sodium typically forms cations with an oxidation state of +1. Potassium typically forms cations with an oxidation state of +1. Magnesium typically forms cations with an oxidation state of +2. Manganese can form cations with oxidation states of +2, +3, +4, +6, and +7, depending on the compound and conditions.
The formula for cobalt(II) fluoride is CoF2, where cobalt has a +2 oxidation state and fluorine has a -1 oxidation state.
Silver metal, Ag has an oxidation number of 0. The most common oxidation state in compounds is +1 (as in AgCl) There are compounds such as AgO where the oxidation number is not +1 which actually contains Ag with +1 and +3
Boron itself is a black or dark brown solid. However, in compounds, boron can exhibit a range of colors, depending on its oxidation state and the other elements it is bonded with.

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.
the oxidation state of beryllium is +2
In NH4F, nitrogen has an oxidation state of -3, hydrogen has an oxidation state of +1, and fluorine has an oxidation state of -1.
The oxidation state of oxygen in HOF (hypofluorous acid) is +1. Oxygen typically has an oxidation state of -2 in compounds, but in this case, since fluorine is more electronegative, oxygen has an oxidation state of +1 to balance the charge of the molecule.
Oxidation state of O is -2.Oxidation state of S is +4.
The oxidation state of Boron in BO3^-3 is +3. This is because the overall charge of the ion is -3, and each oxygen atom has an oxidation state of -2. Hence, the Boron atom must have an oxidation state of +3 to balance the charges.
Scandium has a higher oxidation state than calcium. Scandium typically exhibits a +3 oxidation state, while calcium usually shows a +2 oxidation state.
The oxidation state of boron in Na2B4O7 is +3. This is because boron typically exhibits an oxidation state of +3 in its compounds due to its electron configuration and bonding characteristics.
The oxidation state of chlorine in bleaching powder (CaOCl2) is +1. This is because calcium has an oxidation state of +2 and oxygen has an oxidation state of -2, so the total charge must be balanced by the chlorine with an oxidation state of +1.
The oxidation state of phosphate (PO4) is -3. This is because oxygen (O) typically has an oxidation state of -2, so there are 4 oxygen atoms in the phosphate molecule, contributing to a total charge of -8. This leaves the phosphorus atom with an oxidation state of +5 to balance the overall charge to -3.
