Isotopes of the same element must differ in the number of neutrons, not protons. If the isotopes differed in the number of protons, they would be completely different elements.

All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.

Naturally occurring uranium consists of three isotopes: uranium-234, uranium-235 and uranium-238. Although all three isotopes are radioactive, only uranium-235 is a fissionable material that can be used for nuclear power.

This is not easy. For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

Some naturally occurring and artificially produced isotopes are radioactive. The nucleus of a radioactive isotope is unstable; radioactive isotopes spontaneously decay, emitting alpha, beta, and gamma rays until they reach a stability, usually in the state of a different element.

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons.

Naturally occurring elements can be seen as different Elements than man made elements related to differences in chemical properties. For example, the man made elements have origins from protons, neutrons, electrons, particle colliders, accelerators.

['Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. ... ', 'Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752% natural abundance), uranium-235 (0.7198–0.7202%), and uranium-234 (0.0050–0.0059%).']

Isotopes are atoms of an element with the normal number of protons and electrons , but different numbers of neutrons.

All isotopes of a given element share the same atomic number, which is the number of protons in the nucleus. They also have the same number of electrons also. For examples, all the isotopes of oxygen have the same atomic number of 8, though they have different mass numbers-16, 17 and 18.

An isotope is a group whose constituents belong to the same chemical element but have different mass numbers. Carbon has two isotopes: 12C and 13C. Both show the same chemical features because of the same atomic number. But the mass of 13C is larger than that of 12C, because 13C has one more neutron.

Atoms of the same element can have different masses. Isotopes of the same element can have different numbers of protons.

They are the same type of atom, however, because their nucleii have the same number of protons in them. Isotopes of atoms that occur in nature come in two flavors: stable and unstable (radioactive). ... Just so you know, there are also non-Natural (man made) isotopes. These are all radioactive.

Atoms of the same element that differ in their numbers of neutrons are called isotopes. ... Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.

A "stable isotope" is any of two or more forms of an element whos nuclei contains the same number of protons and electrons, but a different number of neutrons. Stable isotopes remain unchanged indefinitely, but "unstable" (radioactive) isotopes undergo spontaneous disintegration.
