Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. From Intro AP Chem ...

Isotopes of the same element have the same numbers of protons in the nucleus but different numbers of neutrons. Since the number of neutrons is different for each isotope of an element then the mass number must also be different for each isotope.

en.wikipedia.org/wiki/Isotope

A neutral atom has the same number of electrons as protons. Thus different isotopes of a given element all have the same number of electrons and share a similar electronic structure. Because the chemical behavior of an atom is largely determined by its electronic structure, different isotopes exhibit nearly identical chemical behavior.

The different isotopes of an element have the same number of protons, as well as the same number of electrons. But the isotopes of an element always have different number of neutrons in their nuclei. The number of protons is also equal to that of electrons for an element.

They have different mass numbers, because they have different numbers of neutrons, and neutrons have a mass of 1, meaning changing the number of them will result in a change in the mass of the element

Which statement concerning elements is true? 1. different elements must have different number of of isotopes 2. different elements must have different number of neutrons 3.all atoms of a given element must have the same mass number 4. All atoms of a given element must have the same atomic number.

simple.wikipedia.org/wiki/Isotope

Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has. Things with different masses have different weights. Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass.

Isotopes of the same element have the same number of protons and electrons when in neutral atomic form. Different isotopes have different numbers of neutrons in their nuclei, resulting in different atomic weights for the different isotopes of a single element.
