Isotopes of an element or compounds formed by isotopes of an element may differ in their:

  1. Atomic mass
  2. Physical and chemical properties
  3. Radioactive decay

What are Isotopes?

Isotopes are atoms that have variable numbers of neutrons but the same number of protons. They have nearly identical chemical properties but differ in mass, which affects their physical characteristics.

How do their properties affect the formation of isotopes of an element?

  • Atomic mass: Isotopes of an element have the same number of protons in their nuclei, but they may have different numbers of neutrons. This means that isotopes of an element will have different atomic masses. For example, carbon-12 and carbon-14 are both isotopes of carbon, but they have different atomic masses because they have different numbers of neutrons in their nuclei.
  • Physical and chemical properties: Isotopes of an element may have different physical and chemical properties because of their different atomic masses. For example, isotopes of an element may have different melting and boiling points, densities, and reactivity.
  • Radioactive decay: Some isotopes are radioactive, which means that they will undergo radioactive decay over time. The rate of radioactive decay is specific to each isotope, so isotopes of an element may have different rates of radioactive decay.

It's worth noting that isotopes of an element or compounds formed by isotopes of an element may also have other differences depending on the specific isotopes in question.

Hence, the answer is atomic mass, physical and chemical properties and radioactive decay.
