Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes. For example, the most common isotope of hydrogen has no neutrons at all; there's also a hydrogen isotope called deuterium, with one neutron, and another, tritium, with two neutrons.
Isotopes are different forms of an element that have different numbers of neutrons.

when you have two different forms of an atom with different masses, it's called an isotope of the atom.
All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. An element has many isotopes--each with a close, but different number of neutrons.
It is called an isotope.
Neutrons. The number of protons is ALWAYS the same for the same element. Different forms of the same element, called isotopes, differ in the number of neutrons only and will react chemically in exactly the same way.
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
They are isotopes of that element, they have different neutron numbers.
It's called an isotope.

Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
yes, they are called isotopes
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.
