Isotope - Wikipedia From left to right, the isotopes are protium (1 H) with 0 neutrons, deuterium (2 H) with 1 neutron, and tritium (3 H) with 2 neutrons Isotopes are distinct nuclear species (or nuclides) of the same chemical element
Isotope | Examples Definition | Britannica 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
What Is an Isotope? Definition and Examples Isotopes share the same chemical properties but may have different nuclear stability and physical properties Some isotopes are stable, while others are radioactive and undergo decay Scientists use isotopes in medicine, archaeology, power generation, and scientific research
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
What are Isotopes? | IAEA 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
