What are oxidation numbers for kids?
From Academic Kids. The oxidation state or oxidation number is defined as the sum of negative and positive charges in an atom, which indirectly indicates the number of electrons it has accepted or donated.
How do you define oxidation number?
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom. Related Topics: oxidation-reduction reaction.
How do oxidation numbers work?
The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
How do you remember oxidation numbers?
The best way to memorize the oxidation number of an ion or radical is to know which elements or compound they are usually in partner with. Knowing the partners you will know the oxidation number.

How do you find the oxidation number examples?
Net oxidation state of Cl2O = 2 x Oxidation state of chlorine + 1x Oxidation state of oxygen = 0. Oxidation state of oxygen = -2. Oxidation state of Cl2O5 = 2 x Oxidation state of chlorine + 5 x oxidation state of oxygen = 0. Oxidation state of oxygen = -2.

Why is it called oxidation number?
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.
