The number of nucleons in an atom can vary. A nucleon is either of the two components that make up an atomic nucleus. That's either a proton or a neutron. Different atoms have different numbers of nucleons, and even different atoms of a given element can have different numbers of nucleons (because of isotopic variation). Let's look an a couple of examples to make our point.
In hydrogen-1, which is the simplest and most common form of hydrogen, there is one proton in the nucleus of the atom. It has 1 nucleon. In hydrogen-2, there are a proton and a neutron in the nucleus, and that's 2 nucleons. In hydrogen-3, there are a proton and two neutrons in that nucleus, and that's 3 nucleons. In helium-3, there are two protons and a neutron in the nucleus, and that's 3 nucleons. You can see what's happening if you think it through.
