Aluminum and chlorine react to form an ionic compound. Similarly, nonmetals (especially those in groups VIA and VIIA, and, to a lesser extent, those in Group VA) can gain the number of electrons needed to provide atoms with the same number of electrons as in the next noble gas in the periodic table. Starch molecules contain many glucose molecules, joined together in long chains with branches. Since most of the pretreatment strategies are cost/energy intensive and environmentally hazardous, there is a need for the development of an environment-friendly pretreatment process. A covalent bond is a bond that results from the sharing of pairs of electrons between two atoms. Two aluminum ions, each with a charge of 3+, would give us six positive charges, and three oxide ions, each with a charge of 2, would give us six negative charges.
