The given table shows the number of protons, neutrons and electrons in atoms or ions. Which atom/ion in the table is an isotope of the atom with the composition of 11 p, 11 e and 14 n?

A

`P`

B

`Q`

C

`R`

D

`S`

Text Solution

Verified by Experts

The correct Answer is:
A
Isotopes are the atoms of the same element with different mass numbers i.e., they have same number of protons but different number of neutrons. Mass number = No. of protons + No. of neutrons Mass number of the given atom = 11 + 14 = 25
