match each vocabulary word to its definition.
an atom that has gained or lost electrons.
atoms of the same element with varying numbers of neutrons.
the weighted average of the masses of all naturally - occurring isotopes of an element.
a negatively charged ion.
a positively charged ion.
cation
average atomic mass
anion
isotopes
ion

Explanation:

1. "An atom that has gained or lost electrons" matches "Ion" because an ion is defined as an atom (or molecule) with a net electric charge due to loss or gain of electrons.
2. "Atoms of the same element with varying numbers of neutrons" matches "Isotopes" as isotopes are atoms of the same element differing in neutron count.
3. "The weighted average of the masses of all naturally occurring isotopes of an element" matches "Average atomic mass" as this is the definition of average atomic mass.
4. "A negatively charged ion" matches "Anion" since anions are ions with a negative charge (gained electrons).
5. "A positively charged ion" matches "Cation" as cations are ions with a positive charge (lost electrons).

Answer:

• An atom that has gained or lost electrons: Ion
• Atoms of the same element with varying numbers of neutrons: Isotopes
• The weighted average of the masses of all naturally occurring isotopes of an element: Average atomic mass
• A negatively charged ion: Anion
• A positively charged ion: Cation
