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

Question

• Their number of protons differ.
© Their atomic masses differ.
• The number of neutrons are the same.
• They are radioactive, like all isotopes.

Answer 1

The correct statement among the options provided is:

• Their atomic masses differ.

Neon-20, neon-21, and neon-22 are isotopes of neon, meaning they have the same number of protons (which is 10 for all neon isotopes) but different numbers of neutrons, leading to different atomic masses.
