Question

what happens to an atom when it gains electrons?
a it becomes a positively charged ion.
b it becomes a different element.
c it remains a neutral atom.
d it becomes a negatively charged ion.

Explanation:

Electrons are negatively - charged particles. When an atom gains electrons, the number of negative charges exceeds the number of positive charges (protons), resulting in a net negative charge. This makes the atom a negatively - charged ion, called an anion. Changing the number of electrons does not change the element (which is determined by the number of protons), and it does not remain neutral as the charge balance is disrupted.

Answer:

d. It becomes a negatively charged ion.
