Contains atoms of more than one element
WebAn atom consists of two regions. The first is the tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, uncharged, particles called neutrons. The second, much larger, region of the atom is a “cloud” … WebA compound, on the other hand, must involve an atom bonding with atoms of two or more different elements. It thus always contains more than one type of element; its constituent parts combine in a fixed ratio. This information holds with the initial statement that all compounds are molecules, but not all molecules are compounds.
