An anion made up of a single element has accepted electrons.

True
False

True

Explanation:

An ion in a molecule is formed with a net electrical charge. The electric charges are generated when the transfer of electrons takes place. In an ionic compound, a single element gains electrons (anion), and other elements lose electrons (Cation).

An anion is made when an element accepts or gains electrons and acquires a negative charge. Halogens such as fluorine, chlorine, bromine, and iodine always form anions, and some nonmetals also form anions such as carbon,  oxygen, and sulfur.

Hence, the given statement is True.
