An ion A. is an ion with a negative charge
B. attracts ions with a negative charges
C. results when an alkaline-earth metal loses one of its outermost electrons
D. has more protons than electrons

C. results when an alkaline-earth metal loses one of its outermost electrons

Explanation:

An ion can be said to result when an alkaline - earth metal loses one of its outermost electrons.

Ions are charged substances that takes part in chemical reaction.

An an atom is neutral substance that is a component of an element. An ion is charged substance. In an ion, the number protons and electrons are unbalanced. The number of protons in an atom are the positively charged particles. The number of electrons are the negatively charged particles.

When there is an inequality between the number of protons and electrons within an atom, an ion forms.
