Periodic Table Trends
 Distinguish metals from non metals using properties
 Recognize elements in the alkali, alkaline earth, halogen, and noble gas families.
 Describe how hydrogen is a “family of one”
 Explain the difference between “families” and “periods” on a periodic table.
 Explain the difference between atomic number and mass number
Atomic Structure
 Describe the subatomic particles, where they are found in the atom, their charges,
and relative mass.
 Calculate number of protons, electrons, and neutrons for atoms (neutral) and ions
(charged).
 Identify the number of valence electrons of an element.
 Understand the difference between isotopes of the same element.
 Draw Bohr models for the first 20 elements
 Draw Lewis models for the first 20 elements
 Draw and interpret Bohr models for simple ionic and covalent compounds.
 Draw and interpret Lewis diagrams for simple ionic and covalent molecules. (e.g.
NaCl, MgO, H2O, CH4, NH3)
 Distinguish between lone pairs and bonding pairs of electrons in molecules.
Chemical Formulas and Equations
 Understand what a chemical formula tells us about a compound
 Give the charge of an ion when an element gains or loses electrons
 Determine how many electrons an element will gain or lose
 Draw electron transfer diagrams of ionic compounds
 Use combining capacities to write formulas of ionic compounds
 Write formulae and names of simple ionic compounds, multivalent ionic compounds,
and compounds with polyatomic ions.
 Write formulae and names of covalent compounds. (need to memorize prefixes!)
 Differentiate between ionic and covalent bonding.
 Know the 8 naturally occurring diatomic gas molecules (N2, O2, F2, Cl2, Br2, I2, At2, H2)
Acids and Bases
 Differentiate between acids, bases, and salts.
 Explain what indicators are used for and how they help determine if a substance is
acidic or basic.
 Explain the significance of the pH scale.
 Find the names and formulas of common acids in your data booklet (e.g. HCl, H2SO4,)
Chemical Reactions
 Describe the difference between a physical and a chemical change
 Write the word equations for a chemical reaction
 Write the balanced chemical equation using chemical symbols and symbols to
indicate the state of each chemical
 Define and explain the law of conservation of mass
 Identify and predict the products of the following types of chemical reactions:
Synthesis, Decomposition, Single replacement, Double replacement, Combustion,
and Neutralization
 Explain how factors such as temperature, concentration, presence of a catalyst, and
surface area can affect the rate of chemical reactions.
Organic Compounds
 Differentiate between organic and inorganic compounds
 Be able to recognize which is organic/inorganic based on the compound’s name,
chemical formula, or from a diagram/model of the compound.
