It is a gas. Generally it shows -2 oxidation number.
Number for hydrogen is +1.Number for sulphur is +6.Number for oxygen is -2.The oxidation number for the overall ion is -1. Oxidation numbers for hydrogen and oxygen are +1 and -2 respectively. By balancing the charges, the sulfur atom is in +6 state.
the most common oxidation number for oxygen is -2.
In H2O, each hydrogen atom has an oxidation state of +1. Since the overall charge of the molecule is zero, the oxygen atom must have an oxidation state of -2 to balance out the charges and make the molecule neutral. This is a common rule based on the electronegativity of oxygen.
Bromine has an oxidation number of negative one, except when with oxygen or flourine.
The oxidation number for Pb in PbO2 is +4. Oxygen in compounds is typically -2, so with two oxygens, the total oxidation number contributed by oxygen is -4. This means that the oxidation number of Pb must be +4 to balance the charges.
Oxygen is a p block element. It shows -2 number commonly.

In HClO2, the oxidation number of hydrogen (H) is +1 since it is typically +1 in compounds, the oxidation number of chlorine (Cl) is +3, and the oxidation number of oxygen (O) is -2. The sum of the oxidation numbers in a compound must equal zero, so in HClO2, the oxidation number of chlorine (+3) is balanced by the oxidation numbers of hydrogen (+1) and oxygen (-2).
It depends on the compound. Lead can have an oxidation state of either 2+ or 4+
The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.
The oxidation number of Fe in Fe2O3 is +3 because oxygen typically has an oxidation number of -2 and there are 3 oxygen atoms for every 2 iron atoms in the compound, making the overall charge -6 for oxygen. To balance the charges, each iron atom must have a charge of +3.
The oxidation number of calcium in the compound CaOCl2 is +2. In compounds, the sum of the oxidation numbers must equal zero, and since oxygen has an oxidation number of -2 and chlorine has an oxidation number of -1, the calcium ion must have an oxidation number of +2 to balance the charges.
The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
