Question

Can two atoms with the same mass number ever be isotopes of each other

Answer 1

No, two atoms with the same mass number can never be isotopes of each other.

Step-by-step explanation:

Isotopes always have different mass number and same atomic number. Mass number is the sum of the number of protons and the number of neutrons. Atomic number is the total number of protons. Therefore, isotopes have different number of neutrons but same number of protons. For example, the three isotopes of hydrogen are ¹₁H,²₁H and ³₁H.

Answer 2

Two atoms with the same mass number cannot ever be isotopes of each other. If two atoms have the same mass number, then they can be the same element or they have different number of protons and with different number of neutrons. Isotopes are atoms which has the same number of protons in the nucleus but they have different number of neutrons.
