Question

process of forming anions
how are anions formed from elements?
these elements gain negatively charged electrons.
these elements lose negatively charged electrons.
these elements lose positively charged protons.
these elements gain positively charged protons.

Explanation:

Anions are negatively - charged ions. They are formed when an element gains negatively - charged electrons. Losing electrons forms cations, and changes in protons are not involved in the formation of simple ions in this context.

Answer:

These elements gain negatively charged electrons.
