JEE Main 2022 — Structure Of Atom Question with Solution

From: JEE Main 2022 (Online) 27th July Morning Shift

Question

Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Energy of orbital of hydrogen atom is greater than that of orbital of lithium.

Reason R: Energies of the orbitals in the same subshell decrease with increase in the atomic number.

In the light of the above statements, choose the correct answer from the options given below.

Correct answer
ABoth A and R are true and R is the correct explanation of A.

Step-by-step explanation

As the atomic number increases then the potential energy of electrons present in same shell becomes more and more negative. And therefore total energy also becomes more negative.



Energies of the orbitals in the same subshell decreases with increase in atomic number.
