Hydrogen.....
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
That varies depending on the element: e.g. hydrogen has 1 proton, uranium has 92 protons.
Every nucleus (except for Hydrogen) consists of protons and neutrons. The hydrogen nucleus is only a proton.

Hydrogen has just one proton. If the nucleus also has a neutron, the isotope is called Deuterium.
helium with 2 proton Hydrogen has 1 proton.
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
