C.3.1 Investigate the observable characteristics of elements, ionic, and covalent compounds. Examine conductivity, solubility, melting boiling point, etc. using lab data and observations Elements – smallest unit of matter that maintains its unique properties compounds – chemical compound comprised of ions held together by electrostatic forces Covalent compounds – two or more nonmetal bonded by sharing valence electrons Patterns Structure and function C.3.2 Compare and contrast how ionic and covalent compounds form. Ionic compounds – chemical compound comprised of ions held together by electrostatic forces Covalent compounds – two or more nonmetal bonded by sharing valence electrons Structure and function Systems and system models C.3.3 Draw structural formulas for simple molecules and determine their molecular shape. Introduction to drawing structural formulas and simple molecular shapes emphasizing three dimensional molecules (water is bent because of lone pairs of electrons) Structural formulas – a formula that shows the arrangement of atoms in the molecule of a compound Molecules – group of atoms held together by chemical bonds Molecular shape – three dimensional arrangement of the atoms bonded in a molecule System and system models C.3.4 Write chemical formulas for ionic compounds and covalent compounds given their names and vice versa. Writing formulas and naming compounds for simple binary and binary covalent compounds Chemical formula – set of chemical symbols showing the elements present in a compound and their relative proportions Patterns System and system models
