SI unit for amount of substance, defined as the number of atoms in exactly 12 g of carbon-12. One mole of a molecular compound contains Avogadro's number molecules and has a mass equal to the substance's molecular weight, in grams.
Uglerod-12 izotopining aynan 12 grammidagi atomlar soni kabi aniqlanadigan moddaning miqdori uchun SI birligi. Har qanday molekulyar tuzilishli 1 mol modda Avagadro soniga teng molekulalarga va molekulyar massaga teng og'irlikka to'g'ri keladi.
A class of bitter-tasting, basic organic compounds with nitrogen-containing rings. Alkaloids often have powerful effects on living things. Examples are cocaine, nicotine, strychnine, caffeine, and morphine.
Tarkibida azotli halqa tutuvchi, achchiq ta'mli organik asos birikmalar. Alkaloidlar asosan jonli narsalarga kuchli ta'sir etadi. Alkaloidlarga kokain, nikotin, strixnin, kafein va morfinlarni misol qilib keltirish mumkin.

Energy is an abstract property associated with the capacity to do work .
Energiya ishni bajarish uchun zarur quvvat bo'lib, u mavhum tushuncha hisoblanadi.
A reaction where a substance loses electrons, called oxidation,
Modda elektronlarini yo'qotgan reaksiyalarga oksidlanish reaksiyalari deyiladi.
The combined mass (as given on the periodic table) of all the elements in a compound.
Birikma tarkibidagi barcha elementlarning massalari (davriy jadvalda berilgan) yig'indisi molekulyar massani beradi.
parent isotope-Or parental isotope, is an element undergoing a nuclear decay, or destruction
Yadroviy parchalanishga yoki bo'linishga uchraydigan izotop.
The number of digits to the right of the decimal point in a number.
O'nli nuqtaning o'ng tomonidagi raqamlar.
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.
Energy an object has because of its mass and velocity. Objects that not moving have no kinetic energy. (Kinetic Energy=0.5* mass*velocity2.
Buyumning og'irligi va tezligiga bog'liq energiya. Harakatsiz buyum kinetik energiyaga ega bo'lmaydi.(Kinetik energiya = 0,5 * og'irlik * tezlik2.
