25 The chemical process in which electrons are gained by an atom or an ion is called(1) addition (3) reduction
(2) oxidation (4) substitution

It is the process of reduction. If you want to remember it, I recommend remember that gaining electrons 'reduces' charge, by increasing the negative number... If that makes sense XD

Answer: Option (3) is the correct answer.

Explanation:

In the process of oxidation, an atom loses electrons or an increase in oxidation number of the atom occurs.

For example, [tex]Cu(s) \rightarrow Cu^{2+}(aq) + 2e^{-}[/tex] is an oxidation process.

Whereas in a process of reduction, an atom gain electrons or a decrease in oxidation number of the atom occurs.

For example, [tex]2Ag^{+} + 2e^{-} \rightarrow 2Ag(s)[/tex] is a reduction process.

Thus, we can conclude that the chemical process in which electrons are gained by an atom or an ion is called reduction.
