It has 234.
1, because it has an atomic number of one, meaning it has 1 proton & 1 electron. It takes 2 electrons to fill the first electron shell, but hydrogen only has 1. So it remains at the 1st shell.

Just 1 shell.
1 electron
There would be only 1 electron in a hydrogen atom because hydrogen only has 1 proton.
