Question

ANS THIS QUESTION AND I WILL MARK AS BRAINLIEST!!


Energy of an electron H-atom in the ground state

is -13.6 eV, hence its energy in the second excited state

is

Answer 1

the energy of second excited state is
since its in ground state, n=1
the first excited state, n=2
then second excited state,n=3

since,
energy=
[tex] - 13.6 \div {n}^{2} \\ - 13.6 \div 9 = - 1.51ev
