To Do… http://chem.illinois.edu/clc Chapters 2 and 3 for discussion tomorrow. Before the next lecture, read Sections 8-1 through 8-6 and begin text hw. Electronic homework (OWL) due Friday (tomorrow) by 10 pm.

Particulate Nature of Matter Atom: smallest part of an element that is still that element (fundamental unit of which elements are composed). Molecule: Two or more atoms joined and acting as a unit. (element or compound)

Chemical Reaction Electrolysis of water demo

Physical Changes

Using The Periodic Table Element: neutral; defined by the number of protons. Ions: positive or negatively charged; comes from a differing number of electrons. Isotopes: atoms of the same element with differing number of neutrons.

Forming a Cation

Forming an Anion

Isotopes of Sodium

Using The Periodic Table Symbol, name, number of protons (all of these are related). Number of electrons in a neutral atom or in a common ion.

Using The Periodic Table

Using The Periodic Table

Using The Periodic Table Formulas of some ionic compounds. Naming simple compounds.

Three Types of Binary Compounds Metal (Groups 1,2,3; Type I) and nonmetal Simple naming: sodium chloride [NaCl], calcium bromide [CaBr2]. Metal (transition; Type II) and nonmetal Roman numerals: iron(II) oxide [FeO]. Two nonmetals Prefixes: carbon dioxide [CO2].

Using The Periodic Table

Three Types of Binary Compounds CaO CoO CO

Three Types of Binary Compounds CaO calcium oxide CoO cobalt(II) oxide CO carbon monoxide

Type I Compound CaO calcium oxide

CaO calcium oxide Charge Balance: Ca2+ O2- (2+) + (2-) = 0 Type I Compound CaO calcium oxide Charge Balance: Ca2+ O2- (2+) + (2-) = 0

Type II Compound CoO cobalt(II) oxide

Type II Compound CoO cobalt(II) oxide

Type II Compound CoO cobalt(II) oxide Co2+ O2- (2+) + (2-) = 0 Co2O3 cobalt(III) oxide Co3+ O2- 2(3+) + 3(2-) = 0
