Question

Identify the similarity between isotopes of the same element.

• A. They have the same particles in the nucleus.
• B. They have the same number of neutrons.
• C. They are equally abundant in nature.
• D. They have the same number of protons
• E. They have the same mass.

Answer 1

The correct option is D They have the same number of protons

Isotopes of the same element must have same number of protons but different number of neutrons and hence they have different mass.

Also the isotopes of same element are not equally abundant in nature.
