You Will Need: 1.Pencil, Text Book Periodic Table 2. Colored Pencils 3. Electrons and Chemical Bonding- 2 pages-4 sides (Pick-up from bookshelfPlease Staple) 4. Balancing Equations #1Due Today 1. The substances on the left side of a chemical equation are called this….. 2. What is the number called in front of a chemical formula that tells you how many models to build? 3. What Law states you can neither create or destroy matter? 4. The substances on the right of the chemical equation are called this…… 5. What type of substance slows down or stops a chemical reaction? 6. Numbers in a formula that represent the number needed of each atom in a compound are called this…… 7. Why are elements’ atoms on the periodic table neutral? 8. The number of electrons on the outermost shell of an atom is called the atom’s ___________. 9. How many more bonds does Nitrogen need to have a full outer shell? 10.Where are the Rare Earth Metals located on the periodic table? Chemical Bonding is the joining of atoms to form new substances. The properties of these new substances are different from the properties of the original elements. Not all the electrons in an atom are used to make chemical bonds. Valence Electrons that determines how atom will react. (bond) 1. Usually between Metals and Nonmetals 2. Transfer of electrons – forming IONS 3. Form Crystal lattices 4. Brittle 5.
