Question

How does an atom of aluminum become an ion?
a. It gains 3 electrons
b. It gains 3 protons
c. It loses 3 electrons
d. It loses 3 neutrons

Answer 1

Answer:

it loses 3 electrons

Explanation:

Initially, the aluminum atom had a charge of +13 + (−13) = 0; in other words, its charge was neutral due to the equal numbers of protons and electrons. When it becomes an ion, it loses 3 electrons, leaving behind only 10. Now the charge is +13 + (−10) = +3.
