- 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
- 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
- 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 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
- 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
- What are Isotopes? - BYJUS
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
