Question

What is the defining characteristic that differentiates isotopes of the same element?
Options
A Different number of protons.
B Different number of electrons.
C Different number of neutrons.
Correct Answer
D Different atomic number.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text defines isotopes as 'variants of elements having a different nucleon number (also known as the mass number A)' and explicitly states that 'Isotopes of an atom have the same number of protons but differ in the number of neutrons.'

Hint

The term 'isotope' implies a variation within the same element, meaning the proton count (and thus atomic number) must be the same.
