###
Periodic Table Families

Given descriptions or specific element groups, students will use a Periodic Table to relate properties of chemical families to position on the table.

###
Atomic Theory: Dalton, Thomson and Rutherford

Given scenarios or summaries of historical events leading to modern-day atomic theory, students will identify the author and experimental design of each and the conclusion drawn from these experiments.

###
Covalent Bonding: Electron Dot Diagrams

Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).

###
Nomenclature of Ionic Compounds

Given descriptors, diagrams. or scenarios, students will write and name the chemical formulas of common polyatomic ions and ionic compounds containing main group or transition metals and bases.

###
Mole Conversions

Given descriptions or chemical formula of a substance, students will convert between mass, moles, and particles for a sample of material.

###
Quantifying Changes in Chemical Reactions: Balancing Equations

Given descriptions or chemical formulas of the reactants and the products of chemical reactions, students will apply the law of conservation of mass and manipulate coefficients to balance chemical equations.

###
Quantifying Changes in Chemical Reactions: Empirical Formula

Given the descriptions or chemical formulas, students will use relative masses of elements in substance to calculate and determine the ratio of atoms of each element in a compound so as to determine percent composition or empirical formula.

###
It's All About Cell Theory
