When an atom of an element has a different number of neutrons.
Is an atom of the same element that have different number of neutrons
An isotope is an atom that contains a different number of neutrons. In order for an element to change there has to be a different number of protons.
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.

Yes. Atoms with a different number of neutrons are called isotopes of that atom, but a variation in the number of neutrons does not change what the atom is.

Isotopes.
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.

the atomic mass is the number of protons and neutrons in an atom of an element and the atomic number is the number of protons of an atom of an element.
The number of neutrons present in atoms of an element may differ. Atoms of an element which have different numbers of neutrons are called isotopes. These differ in mass but have the same chemistry.All of the neutrons in the nucleus of an atom are the same.
