The ionization potential of a hydrogen atom is 13.6 eV, which is the energy needed to completely remove the electron from the nucleus when the atom is in its ground state. This value is derived from the Bohr model of the hydrogen atom. Other options like 1.36 eV, 10.2 eV, and 4.3 eV do not match the energy required to ionize hydrogen and are therefore incorrect.

This is the correct ionization potential of a hydrogen atom. It is the energy required to remove an electron from the hydrogen atom in its ground state.

This value is incorrect and significantly lower than the actual ionization potential of hydrogen.

This value is incorrect. Although it is closer to the correct value, it is still not accurate for the ionization potential of hydrogen.

This value is incorrect and does not represent the energy required to ionize a hydrogen atom.
