Isotope - Wikipedia 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 different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei
Isotope | Examples Definition | Britannica What is an 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 Every chemical element has one or more isotopes Why do isotopes have different properties?
What Is an Isotope? Definition and Examples - Science Notes and Projects 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
ISOTOPE Definition Meaning - Merriam-Webster The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties
What are Isotopes? | IAEA - International Atomic Energy Agency 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 forms of a chemical element with specific properties You can see the different chemical elements on the periodic table
Isotope Definition and Examples in Chemistry - ThoughtCo 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
Isotope Basics | NIDC: National Isotope Development Center 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
DOE Explains. . . Isotopes | Department of Energy Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons The number of protons in a nucleus determines the element’s atomic number on the Periodic Table For example, carbon has six protons and is atomic number 6
What Is an Isotope? | HowStuffWorks An isotope is an atom of an element that has a different number of neutrons than other atoms of that element Examples of isotopes include hydrogen-1 (protium), carbon-12 (C-12), and carbon-14 (C-14)
What are Isotopes? - BYJUS Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons
