Atomic Mass minus atomic number.
This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons.
The atomic number of an element is simply the number of protons in the atom.
So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.
Isotopes. They differ in the number of neutrons in the nucleus.
The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U
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. so it should have different mass numbers..

Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
Isotopes. They differ in the number of neutrons in the nucleus.
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
All carbon isotopes have the same number of neutrons.
Isotopes have a different number of neutrons.
Isotopes have different number of neutrons.

Neutrons of course?!
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
