Question

If the energy of second Bohr orbit of the hydrogen atom is –328 kJ mol–1, then the energy of the fourth Bohr orbit would be

Answer 1

Here is your answer

Energy of second bohr orbit of the hydrogen atom is -328 kj/mol.

The energy of hydrogen atom is inversely proportional to square of principle quantum no.

the energy of fourth bohr orbit would be=(-328/4)=-82 kj/mol

If the electron jumps to fourth orbit from second orbit then it will absorb -82 kj/mol energy. Thus we can determine energy of hydrogen atom by Bohr's atomic model.
