Detailed explanation-1: -Atoms are in their simplest form. However, since molecules are created from atoms, molecules can be broken down into their individual atoms using chemical reactions to break their bonds. For example, water is made up of hydrogen and oxygen.
Detailed explanation-2: -Compounds can be broken down by using heat or electrical energy. The energy causes a chemical reaction and breaks the bonds holding the atoms together. When the bonds are broken, the compound can become two smaller compounds, or can be broken into individual atoms.
Detailed explanation-3: -A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe.
