Ar\(^ {18}_{40}\) and Ca\(^ {40}_{20}\) are considered as:
Show Hint
Isotopes of an element have the same number of protons (atomic number) but differ in the number of neutrons, leading to different mass numbers.

Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Ar\(^ {18}_{40}\) and Ca\(^ {40}_{20}\) are isotopes because they have the same mass number but different atomic numbers, which means they are atoms of different elements but with the same total number of nucleons.
