Definition of the term isotope
WebIsotope definition, any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different … WebIsotope: An atomic form of an element having a particular number of neutrons. Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic masses, e.g. U-235, U-238. Some isotopes are unstable and decay (qv) to form isotopes of other elements. TOP

WebTerms in this set (14) Isotopes. An isotope is one of two or more species of atoms of a chemical element with the same atomic number. STABLE AND UNSTABLE ISOTOPES. Isotopes utilized in nuclear medicine fall into two broad categories: Stable and Unstable. Stable isotopes do not undergo radioactive decay.

A radioisotope is an energetically unstable atom that will achieve a stable or more stable, lower-energy state (transitioning from a parent to a daughter state) by releasing (radiating) energy (radiation), in some form (e.g., emitting a gamma ray, positron particle, or beta particle, as discussed later). roll vinyl for windowsWebFeb 4, 2024 · The term "isotope" was introduced by the British chemist Frederick Soddy in 1913, as recommended by Margaret Todd.

The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. roll waist maxi skirtWebIsotopes are atoms of the same element with different numbers of neutrons. Because they contain different numbers of neutrons, isotopes have different atomic masses. The average atomic mass of an element is calculated by taking the weighted average mass of the element's naturally occurring isotopes. Created by Sal Khan. roll waist bootleg flare pants
