Warm-Up 3/18/14 Grab a new unit cover sheet for pg. 33 Unit # 10 Title: Chemical Bonds L.O. #1 Identify elements and compounds based on chemical formulae. L.O. #2 Compare and contrast ionic and covalent bonding, and identify which type will form between atoms.

Types of Chemical Bonds Tuesday 3/18/14

Compound: Substance made of 2 or more atoms chemically combined Common Compounds Vinegar Acetic acid HC2H3O2 Sand Silicon dioxide SiO2 Stomach Acid Hydrochloric acid HCl Cane Sugar Sucrose C12H22O8

Chemical Formula Tells what elements a compound contains and the exact # of each type

Forming Compounds Atoms form compounds to become “chemically stable”—fill their outer level of electrons.

Chemical Bond Force that holds together the atoms in a substance.

Two Types of Bonding Ionic Bonding Covalent Bonding Between a metal and nonmetal atom Atoms lose or gain electrons (exchange) Held together by attraction between charged ions Between a nonmetal and a nonmetal Atoms share electrons Atoms can form multiple bonds (share many times)
