Isotope - Wikipedia
https://en.wikipedia.org/wiki/Isotope
WEBIsotopes 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.

WEBIsotopes 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.

WEBSep 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.

WEBIsotopes are atoms of the same element with different numbers of neutrons. Since isotopes of an element have different numbers of neutrons, they also have different masses. The sum of the number of neutrons and protons in an atom is called its mass number. Isotopes can be represented in writing using isotope notation. Created by Khan Academy.

WEBFeb 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.
