If you are referring to the valence shell; the answer is one.
Hydrogen has only one electron shell; the ionization energy is 1 312 kJ/mol.
If you mean the energy levels of the electron shells: it doesn't have one.
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
valence electrons are the electrons in the outermost energy level

The outermost principle energy level for strontium is the 5th energy level.
How much unoccupied spaces in the outermost level in hydrogen ?
The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.
Electrons are those found in the outermost energy level of an atom?They are called valence electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Halogens have six valence electrons in the outermost energy level.
valence electrons are the electrons in the outermost energy level
Outermost energy level is full if there are 8 electrons in the valence shell.
