An isotope is a distinct nuclear species of the same chemical element with different numbers of neutrons in its nucleus. Learn about the history, notation, variation, occurrence and uses of isotopes in nuclear physics, chemistry and biology.
13 wrz 2019 · Isotopes are forms of an element that have different numbers of neutrons and atomic masses. Learn how to write and identify isotopes, and the difference between stable and radioactive isotopes.
19 sie 2022 · Learn about the different types of isotopes, their properties and uses, and how the IAEA helps countries to apply isotopic techniques. Find out how isotopes are used in water, land, food, health, environment and more.
Izotopy, ze względu na stabilność, dzieli się na: trwałe – nieulegające samorzutnej przemianie na izotopy tego samego lub innych pierwiastków. nietrwałe, zwane izotopami promieniotwórczymi – ulegające samorzutnej przemianie na inne izotopy, zazwyczaj innego pierwiastka.
Odmiany danego pierwiastka, które różnią się liczbą neutronów nazywamy izotopami. Charakteryzują się one zatem taką samą liczbą atomową, ale różną liczbą masową. Mają one natomiast identyczne rozmiary atomów, ponieważ wszystkie mają jednakową ilość elektronów.
Learn about isotopes, atoms of the same element with different numbers of neutrons, and how they affect relative atomic mass. Find out the names, symbols and properties of three isotopes of hydrogen and two isotopes of chlorine.
