When an atom in a reactant loses electrons, what happens to its oxidation number?

OA. Its oxidation number decreases.

0

OB. Its oxidation number doubles.

0

C.

Its oxidation number increases.

0

OD. Its oxidation number increases by one.

O E.

its oxidation number stays the same.

The answer to your question is: C

Step-by-step explanation:

A. Its oxidation number decreases. If the oxidation number decreases, if becomes more negative then it would not be losing electrons it would be gaining electrons.

B. Its oxidation number doubles. this option is wrong, it depends on the elements what happens with the oxidation number.

C. Its oxidation number increases. When an atom loses electrons, it becomes more positive, then the oxidation number increases.

D. Its oxidation number increases by one. This option is wrong, it depends on the element if it increases or not.

E. its oxidation number stays the same. The oxidation number changes when it loses electrons
