Energy required for the electron excitation in Li⁺⁺ from the first to the third Bohr orbit is:

A. 12.1 eV
B. 36.3 eV
C. 108.8 eV
D. 122.4 eV

Answer :

Final answer:

The energy required for the electron excitation in Li2+ ion from the first to the third Bohr orbit is 108.8 eV, calculated based on the energy differences of the orbits provided. The correct option is c.

The energy required for the electron excitation in Li2+ ion from the first to the third Bohr orbit can be calculated using the energy differences of the orbits provided. The energy difference from the first to the third orbit is -27R (negative of -27R) + R, where R corresponds to the Rydberg constant. With the given information, the energy required for this excitation is 108.8 eV.
