A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. In this case, NH4 + and SiCl4, both have 4 molecules attached to their respective central atoms. The two electrically charged regions on either end of the molecule are called poles, similar to a magnet having a north and a south pole. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O 2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H 2 O).
