noun
- 1. each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element: "some elements have only one stable isotope"

An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.
Sep 13, 2019 · An isotope refers to a sample of atoms. When the number of protons and neutrons of an individual atom is studied, it is called a nuclide of the element. In nuclear science, the term nuclide is preferred over the term isotope. Nuclides with the same mass number as each other are called isobars.
Isotopes are distinct nuclear species (or nuclides) of the same chemical element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but differ in nucleon numbers ( mass numbers) due to different numbers of neutrons in their nuclei.
An isotope is a variation of an element that possesses the same atomic number but a different mass number. A group of isotopes of any element will always have the same number of protons and electrons. They will differ in the number of neutrons held by their respective nuclei.
Aug 19, 2022 · Isotopes are forms of a chemical element with specific properties. Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element.
Isotopes 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.
Feb 4, 2020 · Isotopes are samples of an element with different numbers of neutrons in their atoms. The number of protons for different isotopes of an element does not change. Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. Radioactive isotopes undergo decay.
An isotope is defined by the number of protons and neutrons in its nucleus, not by the number of electrons. Carbon atoms have 6 protons, but they can have different numbers of neutrons, such as 6, 7, or 8. These are called carbon-12, carbon-13, and carbon-14, respectively.
Isotopes are atoms of the same element that have the same number of protons (i.e., atomic number, "Z") but a different number of neutrons, meaning that their mass number, "A", varies. Take hydrogen, for example.
Isotopes are atoms of the same element, meaning they have the same number of protons and electrons but that have different numbers of neutrons. The different numbers of neutrons give isotopes different masses.
