Review forMrs - Twinsburg



Review for Chemistry SLO Final Exam with Mr. Witting

Measurements

o SI Units (mass = grams (g),

volume = Liter (L), etc.)

• Significant figures

o Calculating significant figures rules:

▪ Addition/Subtraction

▪ Multiplication/Division

• Metric Conversions

o Metric Timeline

▪ L → mL, Kg → g, etc.

• Density (D = m/V)

o Mass

Volume

Atoms

➢ Atoms

o Atomic # = # of protons

o # of protons = # of electrons

o mass # = protons + neutrons

➢ The periodic table

o Groups = columns

o Periods = rows

o 4 categories

▪ Metals, Nonmetals,

Metalloids and

Noble Gases

o Metal groups

▪ Alkaline, Alkali-earth,

Transition

➢ Periodic trends (How it changes across

the periodic table)

o Electronegativity

➢ Forming ionic compounds

o Criss-Cross method

o Polyatomic ions

(a table will be given to you)

➢ Naming ionic compounds

➢ Isotopes

Stoichiometry

✓ Calculating molar mass (Formula Mass)

✓ Mass-mole, mole-mass relationships

✓ Balancing Chemical equations

Chemical Equations

• Writing balanced formulas

• Know the types of equations:

o Synthesis, Single Displacement, Combustion

Double Displacement, Decomposition

• (Avogadro’s Number)

Acids- Bases

❖ Acid-Base reactions

o Naming and Formulas

❖ Molarity

Electrons

➢ Electron configurations (1s2, 2s2, 2p2, 2p6, etc.)

o How to determine the element from

the electron configuration

➢ Periodic trends (How it changes across

the periodic table)

o Atomic radii

o Ionization energy

o Electronegativity

Covalent Molecules

➢ What is a covalent bond

➢ Drawing Lewis Dot Structures according to the VSEPR theory

➢ Naming covalent compounds

o P5O2 (pentaphosphorus dioxide)

Extras

← Lab Equipment – Identify

← Solubility Rules

← Bond types

• Ionic, Covalent

• Polar, Non-Polar
