Solution

The correct options are
A the first Bohr radius is 0.529 oA
B angular momentum of the electron is expressed as integral multiples of h2π
C the energy of the nth level En is proportional to 1n2
(A) Angular Momentum =nh2π; where, n=1,2,3
(B) a0=0.529A (Fact)
(C) En=(13.6 eV/atom)z2n2 (Fact) En1n2
(D) (E2E1)>(E3E2)>(E4E3) ..... from the above reaction.
