How Interactions Within an Atom Cause Change

There are three types of intermolecular force; covalent, ionic, and metallic. All of them cause a change in the atom. The type depends on the different types of atoms. Ionic bonding happens with metal and nonmetal. Metallic bonding happens with two metals. Covalent bonding lets atoms to share there electrons. The atoms either have to give away electrons or get some from another atom. This all depends on how fart he atom has to move to be in the right spot. Opposite charges pull atoms together and positive charges push atoms apart. (Science@Berkeley Labs, 2009)
