What is a compound?
Substances made up of more than one type of atom or chemical element combined in a fixed ratio. It is a pure substance made of the same type of molecules which are made of several atoms.
What is a mixture?
A substance formed when elements and compounds are combined. A substance made of several types of elements and/or compounds which are mixed (not joined by bonds).
What is a molecule?
It is a group of atoms within compounds which are often small and contain just a few atoms. It is a particle made up of atoms that are bonded together.
What is an element?
Substances that are made up of just one type of atom. Any substance that cannot be decomposed into simpler substances through ordinary chemical processes.
