Question

energy of second bohr orbit of the hydrogen atom is -328 kj/mol hence the energy of fourth bohr orbit would be what

Answer 1

divide the enery of first bohr orbit i.e -1312kj/mol with square of n i.e square of 4 i.e 16.you will get answer as 82kj/mol

Answer 2

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.
