Discussion: Consider the Lewis structure of the carbonate ion, CO 3 2-. It was first prepared about 1620 by the Belgian scientist Jan Baptista van Helmont , and it was first studied in 1772 by the English chemist Joseph Priestley. Hence it is Lewis acid as it can accept lone pair of electrons. Molecules whose central atom can hold more than 8 electrons can also be electron acceptors and are classified as Lewis acids (SiF 4). Although this is useful because water is a common solvent, it is limited to the relationship between the H + ion and the OH − ion. However, it is also a strong oxidizing agent, and solid perchlorate compounds can form metastable complexes which are explosive. The change of one type of matter into another type (or the inability to change) is a chemical property. Drawing the Lewis Structure for BF 3. Dots can be used to represent the shared electrons within the bonds of the atoms, but dashes can be used to represent covalent bonds as well.
