By definition Hydrogen has only one proton.
1H, 2H, and 3H refer to different isotopes of hydrogen, with the number indicating the total number of particles in the nucleus (protons and neutrons). 1H is the most common isotope of hydrogen, consisting of just one proton in its nucleus. 2H is a stable isotope of hydrogen, also known as deuterium, with one proton and one neutron. 3H is a radioactive isotope of hydrogen, also known as tritium, with two neutrons in its nucleus.
Yes, the sum of protons and neutrons in the nucleus of an atom is known as the mass number. The mass number is used to identify different isotopes of an element.
Although the number of protons in the nuclei of the atoms of an element is constant, the number of neutrons varies in general. For instance, hydrogen comes in three forms, known as isotopes, one with no neutrons in its nucleus, one with one neutron and one isotope with two neutrons in its nucleus.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
They differ from each other in the number of neutrons, and therefore also the mass. They will also have different stabilities (for example, some of them may be radioactive), but this is complicated.
The most common form of Hydrogen, forming more than 99.9% of all hydrogen atoms in the universe, (sometimes known as Hydrogen-1) has one proton in the nucleus and one electron ( with no neutrons ). There are, however, other forms (isotopes) of hydrogen that can be stable, such as Hydrogen-2 ( also known as deuterium ), which has one neutron and one proton in the nucleus as well as one electron.

Before we tackle isotopes and neutrons, lets talk about protons. The number of protons in an atom determines the elemental identity of the atom. Only that. Now to the question. Atoms of a given element have a specific number of protons in the nucleus, but can have a modest variety of numbers of neutrons in their nuclei. Let's look at hydrogen. Hydrogen is identified by the fact that there is a single proton in the nucleus. Most hydrogen is just that. But some hydrogen has a neutron stuck to the one proton in the nucleus. This creates another "flavor" of hydrogen. It's another isotope of hydrogen. We have the original isotope of hydrogen (with one proton and no neutron) and the isotope with the one proton and one neutron. Now we look at the last and most unusual isotope of hydrogen. It has the one proton and two neutrons. Hydrogen has three isotopes, and each has the same number of protons (each isotope is hydrogen) and each has a different number of neutrons: zero, one and two. Heavier elements have varying numbers of neutrons in combinations with there protons. This creates a number of different isotopes for each and every element. It is the variable numbers of neutrons that can hang out with the protons in a given element's nucleus that give rise to the different isotopes of that element. Our friends at Wikipedia have some details. A link is provided.
The nucleus contains protons and neutrons, which are collectively known as nucleons. Protons have a positive charge, while neutrons are neutral. These particles are further comprised of quarks, which are elementary particles that make up protons and neutrons.
They are isotopes of one another. The numbers indicate the mass number, which is the product of the number of neutrons and the number of protons. Since they're both hydrogen atoms, we know that they both have one proton. However, 1H has no neutrons while 2H has one neutron. Atoms of the same element with a different number of neutrons are called isotopes.
Helium, The hydrogen atoms fuse to form helium, atomic number 2 and mass number 4. In the illustration, the gray spheres represent neutrons and the orange are protons. The number of protons in the nucleus of any atom determines the identity of that atom. In this case two protons indicate element #2 or helium. This fusion reaction, which occurs in the sun and other stars, also produces an additional neutron and energy.
The nucleon number, also known as the mass number, can be found by adding the number of protons and neutrons in an atomic nucleus. It is represented by the letter A in the notation of an element's isotopes.
The atomic number of an element tells you how many protons an atom has in it's nucleus, and each element is defined by the number of protons it has. For example hydrogen always has 1 proton. The Mass number tells you how many protons and neutrons there are in an atom. However it is possible for an element to have different numbers of neutrons in the nucleus. When this occurs you will get different masses for the same element but the same atomic number. Two (or more) elements are known as isotopes if the only difference between them is the number of neutrons. Probably the most common/well known example of an isotope is Hydrogen, Deuterium (Hydrogen with a neutron) and Tritium (Hydrogen with 2 neutrons)
