(1) gains one electron and becomes a negatively charged ion
(2) gains three electrons and becomes a negatively charged ion
<u>(3) loses one electron and becomes a positively charged ion</u>
<span>(4) loses three electrons and becomes a positively charged ion</span>
Answer: Zinc
Explanation: Zinc has the lowest density. Since density = mass/volume, we can also say volume = mass/density. Given the same masses, the metal with the lowest density would have the largest volume.
