This is not because it cannot carry electricity, but because it conducts electricity poorly. How are ionic and covalent bonds similar? Ionic bonds, on the other hand, form when one atom donates an electron to another atom. The answer is the number of electrons that are being shared. Organic molecules can form ions too ( acids and bases ): ACIDS: molecules that are able to lose a proton (hydrogen ion) easily, such as a carboxyl group (a carboxylic acid): R-CO-OH ---> R-COO- (net charge = -1), + H+. This process is called solvation [Purves6ed 2.11] . glycosidic bonds It contains an excess or deficit of electrons, and hence is highly reactive.
