This is the full question

What is true when an ion is formed?

A There is an unequal number of electrons and neutrons.

B There is an unequal number of electrons and protons.

C The atom loses one or more protons.

D The atom loses one or more neutrons.

B There is an unequal number of electrons and protons.

Explanation:

There are two kinds of ion, cation, and anion. Cathion is when an atom loses electrons, which makes it have more proton than the electron. This makes the charge positive. Anion is the opposite of cathion. It's formed when an atom receives electron, thus making its charge negative. Because of this, there is no ion that has equal electron and protons.
