Best Answer: A compound is something made up of elements (ie not one pure element). The word compound means something made of a combination of things - like a compound sentence or a military compound (made up of several buildings). Elements are the basic substances that make up the universe and cannot be broken down into different substances. Compounds are composed of two or more elements that have bonded to form one substance In short: Elements - cannot be broken down and bond to form compounds Compounds - two or more elements that have bonded to form a unique substance
Certain molecules are also compounds. A compound is a group of two or more different atoms chemically bonded together. What makes compounds special is that there are at least two different elements, or types of atoms in the group.All compounds are molecules, but not all molecules are compounds.ompounds Are Different Elements. Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a group of two or more different atoms chemically bonded together. The key here is that compounds are made of at least two different elements.
