Question

a ____ is a charged particle because it has more or fewer electrons than protons. when an atom __ an electron, it becomes a positively charged ion. when an atom ____ an electron, it becomes a negatively charged ion.
options:

1. isotope, loses, gains
2. ion, loses, gains
3. ion, gains, loses
4. isotope, gains, loses

Explanation:

An ion is a charged particle. When an atom loses an electron, it has more protons than electrons and becomes positively charged. When an atom gains an electron, it has more electrons than protons and becomes negatively charged. Isotopes are atoms of the same element with different numbers of neutrons, not related to charge from electron gain/loss.

Answer:

B. ion, loses, gains
