Question

there are three stable forms of neon: neon-20, neon-21, and neon-22. which statement is true? (1 point) the number of neutrons are the same. they are radioactive, like all isotopes. their number of protons differ. their atomic masses differ.

Explanation:

Neon - 20, neon - 21, and neon - 22 are isotopes of neon. Isotopes of an element have the same number of protons but different numbers of neutrons, resulting in different atomic masses. Neon - 20, neon - 21, and neon - 22 are stable isotopes, not radioactive.

Answer:

The atomic masses differ. So the correct option is: The atomic masses differ.
