izotop – yadroda bir xil sonli protonlarga ega bo'lgan yoki atomning bir xil soniga ega bo'lgan, ammo yadroda turli xil neytronlar yoki turli atomik og'irliklarga ega kimyoviy elementlarning ikki yoki undan ortiq shakllaridan har biri. 81 ta qatlam elementining 275 izotopi mavjud bo'lib, 800dan ortiq radioaktiv izotoplardan tashqari har bir elementning izotopik shakllari ham mavjud. Yagona elementning izotoplari deyarli bir xil xususiyatga ega.		isotope–any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. There are 275 isotopes of the 81 stable elements, in addition to over 800 radioactive isotopes, and every element has known isotopic forms. Isotopes of a single element possess almost identical properties.
