Compounds are made up of atoms which prefer to be associated with each other, than exist on their own. An ionic compound is attracted by electronic forces, a bit like magnets i.e. they have a high attraction for each other, without actually becoming cahnged themselves. Covalent compounds on the other hand are made of atoms , all of which are changed when they come together, like baking the ingredients of a cake- you can't get the original individual components back.
