Isotopes of the same element will have a different number of neutrons, but the same number of protons. t f

True.

Explanation:

Isotopes are defines as different form of an element ( same ) which has same number of protons but have different number of Neutrons.

Because of this property, the relative mass which is defined as the sum of neutron and protons, differ in isotopes.

The isotopic character shows the radioactive form of an element. Isotopes have same atomic number but have different atomic masses.

There are many isotopes found, for example ;

Isotopes of Hydrogen : Protium , Deuterium and Tritium.
