Detailed explanation-1: -An atom is the smallest part of an element that can exist. Compounds are formed from elements by chemical reactions. Compounds contain two or more elements chemically combined in fixed proportions and can be represented by formulae using the symbols of the atoms from which they were formed.
Detailed explanation-2: -In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchanging electrons between atoms.
Detailed explanation-3: -Sometimes more than two elements make up a compound. A sugar molecule (glucose) is a compound of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms, written as C6H12O6. These specific atoms in these exact numbers make up a sugar molecule.
