What is oxidation state and how to find it
Answers
Alternative Title: oxidation state. 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.
The oxidation number of a Group 2 element in a compound is +2. The oxidation number of a Group 17 element in a binary compound is -1. The sum of the oxidation numbers of all of the atoms in a neutral compound is 0. The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
Answer:
The oxidation number of an atom is the charge it appears to have when you count the electrons according to some arbitrary rules. The oxidation number of an atom depends on the other atoms in the substance. For example, In KCl, the oxidation number of Cl is 0. a positive or negative number that represents the effective charge of an atom or element and that indicates the extent or possibility of its oxidation the usual oxidation state of sodium is +1 and of oxygen −2.
