Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant stable isotope(s) of an element have ...

Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium ...

Most elements exist in two or more forms, known as isotopes. Isotopes have the same number of protons but differ in their number of neutrons, resulting in different masses. The lighter form is ...

When world-leading teams join forces, new findings are bound to be made. This is what happened when quantum physicists from ...

The different types of chlorine are called isotopes of chlorine. Key fact Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three ...

Eighty out of the first 82 elements in the periodic table have stable isotopes. Measuring and analysing their distribution allows for many practical applications. The IAEA assists Member States in ...
