A neutral atom of hydrogen has 1 electron.

In more detail:

  • Hydrogen’s atomic number is 1, which means it has 1 proton in its nucleus.
  • In a neutral atom, the number of electrons equals the number of protons, so hydrogen has 1 electron.
  • That single electron occupies the lowest-energy shell (the 1s orbital) around the nucleus.

So, if someone asks “how many electrons are there in an atom of hydrogen?”, the quick scoop answer is: exactly one electron in a neutral hydrogen atom.
