parent isotope-Or parental isotope, is an element undergoing a nuclear decay, or destruction
Yadroviy parchalanishga yoki bo'linishga uchraydigan izotop.
In a nuclear equation the compound remaining after the parent isotope (the original isotope) has undergone decay. A compound undergoing decay, such as alpha decay, will break into an alpha particle and a daughter isotope.
Yadro reaksiyalarida ona izotopning (original izotop) parchalanishidan keyin qolgan izotop. Aralashma, alfa parchalanish kabi bir alfa zarracha va bir qiz izotop hosil qilib parchalanishi.
1. The OH- ion. 2. Compounds containing the OH- ion. See also: hydroxide compounds.
1. OH- ioni. 2. OH- ionlarini o'z ichiga olgan aralashmalar. Shuningdek, gidroksid moddalarni qarang.

The total number of protons and neutrons in an atom or ion. In nuclide symbols the mass number is given as a leading superscript. In isotope names (e.g. carbon-14, sodium-23) the mass number is the number following the element name.
Atom yoki iondagi proton va neytronlarning umumiy soni. Atom og'irligi atom ko'rsatkichlari ichida yetakchi rol o'ynaydi. Izotop nomlaridagi (masalan, uglerod-14, natriy-23) ko'rsatilgan sonlar berilgan elementning og'irliklaridir.
