Oxidation Numbers

Tin (Sn) belongs to Group 14 of the periodic table.

The oxidation number of mercury in the mercurous ion (Hg₂²⁺) is +1. Each mercury atom in the mercurous ion carries a charge of +1.

Oxidation numbers help to identify which atoms are oxidized and reduced in a reaction. If an element's oxidation number increases, it is being oxidized. If it decreases, it is being reduced. By comparing the oxidation numbers of reactants and products, you can determine if a redox reaction has occurred.

The oxidation number of hydrogen (H) is always +1. Since the overall charge of H2Co is 0, the oxidation number of carbon (C) would be +2, based on its common oxidation state in compounds.

The oxidation number of arsenic in H3AsO3 is +3. This is because each hydrogen atom has an oxidation number of +1 and each oxygen atom has an oxidation number of -2, so the three hydrogen atoms have a total oxidation number of +3 and the oxygen atoms have a total oxidation number of -6, leaving the arsenic with an oxidation number of +3 to balance the charge.

The oxidation number of oxygen (O) in MnO4 is -2. To find the oxidation number of manganese (Mn) in MnO4, we use the fact that the sum of the oxidation numbers in a compound is zero (since MnO4 is a polyatomic ion). Therefore, Mn must have an oxidation number of +7 in this compound.

To determine the oxidation number of an element, consider its usual oxidation state based on its position in the periodic table and the known oxidation states of other elements in the compound. In a neutral compound, the sum of the oxidation numbers must equal zero, and in an ion, the sum must equal the charge of the ion. Use these rules to assign the oxidation number of the element.

2nd Opinion: The answer is -2.

Oxidation number of N is +3. Oxidation number of H is -1.

+1 for Hg in the Hg22+ ion

It is equal to the charge. So Oxidation number is +1

Typically in compounds it is -2 (oxide ion) - other values include zero (in O2 and O3)

The oxidation number of phosphorus (P) in the HPO4^2- ion is +5. This is determined by considering that there are four oxygen atoms with a -2 charge each, totaling -8 charge. Since the overall charge of the ion is -2, the phosphorus must have a +5 oxidation number to balance the charges.

The oxidation number of carbon in C25H52 is 0. This is because in organic compounds like hydrocarbons, carbon is typically assigned an oxidation number of 0 due to its equal sharing of electrons with other carbon atoms.

0 in elemental form

+1 in its compounds

Yes, during oxidation, the oxidation number of the substance increases. This is because oxidation involves the loss of electrons, leading to an increase in the oxidation number.

4, 3, 2, 1 (weakly basic oxide)

Maximum Oxidation number: 4

Minimum Oxidation number: 0

Assuming you mean what is the oxidation number of each atom in the compound C3H8O? Oxidation rules state the the sum of all oxidation numbers in a neutral molecule equals 0.

1. O = -2

2. H = +1

3. C = -2

These numbers are derived from...

(-2) + (+1 x 8) + (-2 x 3) = 0

The oxidation number of phosphorus in H4P2O7 is +5. This can be calculated by taking into account the known oxidation states of hydrogen (+1) and oxygen (-2), and solving for the unknown oxidation state of phosphorus to ensure the overall charge of the compound is neutral.

-1 is most common in chlorides.

However chlorine can exhibit oxidation numbers up to +7 in its compounds.

CARBON=0

since there are 2 H atoms, +1 for each = +2

1 O atom, -2 for each = -2

So since that already adds up to 0, carbon will have an oxidation number of 0.

hope this helped a little!

The oxidation number of nitrogen in N2O is +1. This is because oxygen is typically assigned an oxidation number of -2, so the two oxygen atoms in N2O contribute a total oxidation number of -4. Since the overall charge of the compound is 0, the two nitrogen atoms must have a total oxidation number of +4, making the oxidation number of each nitrogen atom +1.

The oxidation number of N in N2O5 is +5. Each oxygen atom has an oxidation number of -2, and since the molecule is neutral, the sum of the oxidation numbers must equal zero, making nitrogen +5.

Nonmetals typically have negative oxidation numbers, which can vary depending on the element and the specific compound. They tend to gain electrons to achieve a stable electron configuration, resulting in negative oxidation states.

0 in elemental form; +1 in all its compounds
