Question

the energy of 2and Bohr orbit of hydrogen atom is-328kj mole the energy of four Bohr orbit would be

Answer 1

Answer:

forth orbit energy = - 82 kj

Explanation:

for second bohr orbit n=2

we have E= -13.6 Z^2/2^2 =

-13.6 Z2/4 = - 328 kj

hence for fourth bohr orbit energy will be one fourth of energy for second orbit

E2 = E/4

E4= E/16

hence

E4 = E2 / 4 = -328 kj / 4 = - 82 kj
