Neutrons.
isotopes of a given element differ in the number of neutrons they have.
The number of neutrons is different.
neutron
Isotopes have a different number of neutrons but the number of protons and electrons is the same.
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..
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
isotopes of a given element differ in the number of neutrons they have.
Isotopes of the same element have different number of neutrons.
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 of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.

No, magnesium is an element. However, it has a number of isotopes.

Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
