Hint :To answer this question, we first need to understand what an electron is. The electron is a subatomic particle with the symbol e or with a negative one elementary electric charge. Electrons are the first generation of the lepton particle family, and because they have no known components or substructure, they are considered elementary particles.
Complete Step By Step Answer:
An electron shell, or energy level, can be thought of as an orbit of electrons around the nucleus of an atom in chemistry. The "K shell" is the one closest to the nucleus, followed by the "L shell," then the "M shell," and so on as you move away from the nucleus. The shells can be identified by letters (K, L, M, etc.) or quantum numbers (n = 1, 2, 3, 4, etc.).
Each shell has a set number of electrons in it —
The first shell, known as the "K shell," has two electrons.
The second shell, known as the "L shell," has eight electrons.
The third shell, called the M shell, has 18 electrons, and so on.
Energy of electron in each energy level is inversely proportional to square of energy level i.e.
$ E = \dfrac{{13.6ev}}{{{n^2}}} $ (Here n is the energy level)
Here finding the energy level in each energy level as given in options –
$ {E_7} = \dfrac{{13.6ev}}{{49}} = 0.277ev $
$ {E_6} = \dfrac{{13.6ev}}{{36}} = 0.377ev $
$ {E_5} = \dfrac{{13.6ev}}{{25}} = 0.544ev $
$ {E_4} = \dfrac{{13.6ev}}{{16}} = 0.85ev $
$ {E_3} = \dfrac{{13.6ev}}{9} = 1.51ev $
$ {E_2} = \dfrac{{13.6ev}}{4} = 3.4ev $
Electronic energy transmission should be highest only when the difference between them is highest
So, by taking data through the energy level as discussed above we can conclude that the max difference is from $ {E_3}{\kern 1pt} {\kern 1pt} {\kern 1pt} to{\kern 1pt} {\kern 1pt} {\kern 1pt} {E_2} $ .
So, the final answer is option (C) i.e., $ 3 \to 2 $ .
Note :
When an atom, molecule, or ion and its electrons are at their lowest potential energy level, they are said to be in the ground state. They are said to be thrilled if their energy level is high. Excitable electrons are those that have a higher energy than the ground state. When more than one quantum mechanical state has the same energy, they are referred to as degenerate energy levels.
