Document: Science Unit 3 (Revised)-6
Abstract: Unit three is Exploring Change, specifically bonds, energy, and reactions. The change to be investigated will include indicators of chemical reactions as they relate to chemical bonding and energy changes. Chapters 7 and 8 cover ionic and covalent bonding respectively, while chapters 9 and 19 are the introduction to stoichiometry, chemical reactions. Again, a review of electronegativity helps explain further the reasons for covalent and ionic bonding.
