Description: 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.

Description: WEBFeb 28, 2024 · isotope, 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 behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

Description: WEBThe word isotope is derived from Ancient Greek: the prefix iso-means "same," while -tope (from the Greek word topos) means "place." The isotopes of a given element always contain the same number of protons and therefore occupy the same place on the periodic table.

Description: 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. Created by Sal Khan. Questions. Tips & Thanks.

Description: WEBWhat are Isotopes? Atoms are composed of a cloud of electrons surrounding a dense nucleus that is 100,000 times smaller and comprised of protons and neutrons. The number of protons (i.e., atomic number, "Z") determines the element; for example, a strontium nucleus always has 38 protons, and a rubidium nucleus always has 37.

Description: 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.

Description: 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.
