How many protons, neutrons, and electrons does hydrogen have?

As its been stated before, Hydrogen has 3 common isotopes, hydrogen (aka "protium", 1 proton, 0 neutrons), deuterium (1 proton, 1 neutron) and tritium (1 proton, 2 neutrons). These isotopes can be found in nature, but I believe the relatively rare tritium is a byproduct of nuclear fission. read more

The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of protons is 1. For zinc, the number of protons is 30. The element of an atom with 2 protons is always helium. read more
