Isotopes are forms of an element with varying numbers of neutrons in the nucleus of the atom. As radioisotopes decay, they slowly transform into other isotopes of the same element through gaining or losing neutrons, and eventually they become other elements entirely. This depends on their decay r...
Now that you know what isotopes are, you can understand exactly whatenrichmentis. Natural Uranium is made up of 99.2745% U-238 and 0.720% U-235, with trace amounts of U-234. While U-238 usually stays together in a neutron field, U-235 readily splits, or fissions, in the presence ...
PET scans use isotopes to highlight functions inside the body. The images produced by isotope scans are made from gamma rays. Gamma rays are given off by the radioactive substance inside the patient. These rays are picked up by a special camera and then sent to a computer. The computer ...
Allotropes are different forms of the same element with distinct physical or chemical properties; Isotopes are atoms of the same element with differing numbers of neutrons.

Isotopes are elements that have the same atomic number (which - as stated above - is what makes them the same element) but different Mass Numbers (A), due to different numbers of neutrons in their nuclei. For more about this seeWhat is an isotope ?
Some isotopes are unstable and tend to decay into other elements, giving off subatomic particles or radiation; these are radioactive and are known as radioisotopes. When scientists refer to a particular isotope of an element, the mass number, or the number of protons plus the number of ...
