The oxidation number of an atom is determined by the number of electrons it gains, loses, or shares when forming a chemical bond. The rules for assigning oxidation numbers are based on the electronegativity of the elements and the structure of the compound. Generally, less electronegative elements have more positive oxidation numbers, while more electronegative elements have more negative oxidation numbers.

What is the oxidation number of Br2?

The oxidation number of Br2 is 0. Each bromine atom in the Br2 molecule has an oxidation number of 0 because the molecule is in its elemental form.


What is the Oxidation number of sulphur in h2s2o8?

The oxidation number of sulfur in H2S2O8 is +6. Each oxygen atom has an oxidation number of -2, and each hydrogen atom has an oxidation number of +1. By setting up an equation and solving for sulfur's oxidation number, you will find it to be +6.


Oxidation in terms of oxidation number?

Oxidation is the process in which an atom loses electrons, resulting in an increase in its oxidation number. This occurs when an element undergoes chemical reactions where it loses electrons to become more positively charged. The oxidation number reflects the number of electrons that an atom has gained or lost in a compound.


What is the oxidation number for HCOO-?

The oxidation number for HCOO- is -1. This is because in the HCOO- ion, the total charge is -1 and each hydrogen atom has an oxidation number of +1, while the carbon atom has an oxidation number of +2 and the oxygen atoms each have an oxidation number of -2.
