Question

which statement describes the process of oxidation? (1 point)
oxidation results in a loss of electrons, so the oxidation number increases.
oxidation results in a gain of electrons, so the oxidation number increases.
oxidation results in a loss of electrons, so the oxidation number decreases

Explanation:

Oxidation is defined as the loss of electrons. When an atom loses electrons, its oxidation number increases. For example, in the reaction \(Na
ightarrow Na^{+}+e^{-}\), sodium (Na) loses an electron. The oxidation number of Na changes from \(0\) (in elemental Na) to \(+ 1\) (in \(Na^{+}\)).

Answer:

Oxidation results in a loss of electrons, so the oxidation number increases.
