How is it possible for two samples of hydrogen to contain the same number of atoms yet have different weights?
What will be an ideal response?
Isotopes are atoms with the same number of protons but different numbers of neutrons. Hydrogen has three isotopes: hydrogen-1, with a mass number of 1; deuterium, with a mass number of 2; and tritium, with a mass number of 3. The mass number is greater in each isotope because the atoms contain an increasing number of neutrons. The heavier hydrogen sample must contain a higher proportion of one or both of the heavier isotopes.
