What is the best definition of "oxidation state"? the number of electrons an atom has the number of neutrons an atom has the number of electrons an atom has relative to a neutral atom of the same element the number of neutrons an atom has the number of electrons and protons an atom has

The number of electrons an atom has relative to a neutral atom of the same element

Explanation:

the oxidation state is a number that indicates the ability to give or receive electrons. This number usually has a sign, which can be positive or negative.

If the oxidation state is a positive number, it means that this atom has the ability to receive such an amount of electrons. If the oxidation state is negative, the element can give that amount of electrons.
