Q

What are compounds?

A

They contain two or more atoms chemically bonded together. This involves giving, taking and sharing electrons to form ions and molecules. Compounds formed from metals and non-metals consist of ions. Compounds formed from non-metals consist of molecules. In molecules the atoms are held together by covalent bonds
