Question

Identify the sets of orbits associated with release of energy
(A) L$\to$M
(B) K $\to$M
(C) L $\to$K
(D) M $\to$L
(E) M$\to$N
(F) N$\to$K

• A. ACD
• B. BCE
• C. CDF
• D. CDE

Answer 1

The correct option is C CDF

Electrons absorb energy to enter into higher energy levels from lower energy levels and release energy in order to enter into lower energy levels from higher ones.

Increasing order of energy levels is given as $K<L<M<N$

Sets associated with release of energy$\Rightarrow \left( C \right)

$L$\rightarrow $K

$\left(D\right)$M$\to$L

$\left(F\right)$N$\to$K

Hence, the correct option is $\left(C\right)$.
