"Molecule" Natural Recordings by Native Speakers
A molecule is the smallest unit of a substance that still retains the properties of that substance. It is a group of two or more atoms that are chemically bonded together. Molecules can be composed of atoms of the same element or of different elements. The atoms in a molecule are held together by chemical bonds, such as covalent or ionic bonds.
I apologize, but there is no word "molebut". It's possible that it's a typo or a made-up word. Could you please provide a different word or correct the spelling of the word you meant to ask about? I'll be happy to help you with its meaning.
