Assertion (A): The ionization energy of Hydrogen atom is -13.6 eV. Reason (R): -13.6 eV is the minimum energy required to free the electron from the first excited state. |
A is false but R is true. Both A and R are true and R is the correct explanation of A. Both A and R are true but R is NOT the correct explanation of A. A is true but R is false. |
A is true but R is false. |
As -13.6 eV is the ground state energy of hydrogen atom which contains only one electron so, this energy will be the same as required to remove an electron from the hydrogen atom's ground state i.e. the ionization energy. |
