Question

if a certain atom gains electrons its oxidation number will be

​

Answer 1

Answer:

The oxidation number of an atom refers to the number of electrons it has lost or gained. Electrons are assigned a negative charge, so by convention if an atom has gained an electron, its oxidation number is reduced. For example, if an atom gains an electron, it has an oxidation number of -1.

Answer 2

If a certain atom gains electrons its oxidation number will be decreased.

Explanation:

• The oxidation number is a hypothetical charge present on an atom of an element.
• As the number of electrons present in an atom of an element changes, the oxidation number of the atom of that element also changes.
• If an atom of an element loses electrons, the positive charge on the atom increases and the oxidation number increases.
• On the other hand, if an atom of an element gains electrons, the positive charge on the atom decreases and the oxidation number decreases.
