Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.

What do most elements contain a mixture of?

Most elements contain a mixture of isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes can have different properties but behave similarly in chemical reactions due to their identical number of protons.

Two atoms have the same number of protons but different numbers of neutrons. What can you conclude about these two atoms?

The atoms are isotopes of each other because they have the same number of protons, making them the same element. The differing number of neutrons results in a difference in atomic mass between the two isotopes.
