An isotope means that there are a different number of neutrons and protons, so if there are two neutrons it means that there is only one proton. That means the mass would be 3.

We all know that from the periodic table, an element with two neutrons has two protons and mass number is number of neutrons + no of protons.

Therefore, the mass number is 4.
