There are three stable forms of neon: neon-20, neon-21, and neon-22. Which statement is true? (1 point)

Their number of protons differ.

The number of neutrons are the same.

Their atomic masses differ.

O They are radioactive, like all isotopes.

1 answer

The true statement among the given options is:

Their atomic masses differ.

Neon-20, neon-21, and neon-22 have different numbers of neutrons, which results in different atomic masses. The number of protons in all three isotopes is the same (10 protons, as all neon isotopes belong to the same element), and they are not radioactive.
