In its ground state, hydrogen has one electron and one proton.
Hydrogen, the first element in the periodic table, has an atomic number of 1. The atomic number represents the number of protons in an atom's nucleus. Since hydrogen has an atomic number of 1, it means it has one proton in its nucleus.
In a neutral atom, the number of electrons is equal to the number of protons. Therefore, hydrogen, with one proton, also has one electron orbiting around the nucleus.
So, in summary, hydrogen in its ground state (before ionization) has one electron and one proton.
