The difference is the number of neutrons contained in the atom's nucleus
isotopes of a given element differ in the number of neutrons they have.
They are called isotopes and the difference between different isotopes of one type of element is the amount of neutrons each have.
Chemical properties are determined by the electron configuration of an atom, not by its mass. These do not differ in all isotopes of one element, because isotopes have the same number of PROTONS thus the same electron configuration. Only the mass of different isotopes of one element is different by the different number of NEUTRONS.
False, different isotopes of the same element have different numbers of neutrons.
Primarily, isotopes differ in the number of neutrons in the nucleus. Secondarily, because some combinations of protons and neutrons produce an unstable nucleus, they may differ by being radioactive.

Isotopes of one particular element (atom) only differ in mass and stability (decay), not in chemical properties.
Isotopes of one particular element differ only in their number of neutrons in nucleus.

An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
They differ in their number of neutrons.Atoms of all isotopes of carbon contain 6 protons and 6 electrons.Carbon-12 is the most common isotope.Isotopes of an element differ because each isotope has a different neutrons, but the same amount of protons.Example: H-1H-2H-1 has 1 neutron, 1 proton, and 1 electronH-2 ,however, has 2 neutrons, 1 proton, and 1 electron.

Yes - by the basic definition of an element; excepting only isotopes of an element, which differ slightly from each other in atomic structure, but not enough to affect the element's outwards physical and chemical properties.
Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.
True, if it contains more than one is is not a single element but a combination of elements. We should include one caveat: elements can have different isotopes of that element. By one definition all the isotopes are still the same "type" of atom since they all have the same number of protons even if they differ in the number of neutrons. If the number of protons differs you no longer have the same element.
