Simply follow the steps below:. The hydrogen has a single electron available for bonding. The atom that has the greater ability to pull electrons towards itself will have an increased number of electrons around it, it will have a slightly more negative charge overall and the end result is a region of the bond that is positive and part of the bond that is negative, thus making the bond polar in nature. It is nonmetallic and tetravalent, making four electrons available to form covalent chemical bonds. Be sure to check the formal charges for the Lewis structure for SO 3. Deuterated chloroform is a deuterated compound that is is an isotopologue of chloroform in which the hydrogen atom is replaced with a deuterium.
