High School Chemistry
Mrs. Cauthron's Guide to Must-Know Facts
Some chemistry you figure out. The rest you just have to know. This is the “just have to know” list — ten topics, with flash cards, quizzes that regenerate, and worked sample problems for each one.
The 10 Must-Know Topics
Pick a topic, read the facts, then hit the practice tools at the bottom of the page. Ten focused minutes beats an hour of re-reading your notes.
Polyatomic Ions
The charged groups that show up in half of every naming question.
Topic 02Metric Prefixes
Kilo to nano — the conversions behind every unit problem.
Topic 03Solubility Rules
Which ionic compounds dissolve, and which crash out as a precipitate.
Topic 04Shapes of Chemical Bonding
VSEPR geometry, bond angles, and why water is bent.
Topic 05Periodic Table Trends
Radius, ionization energy, electronegativity — and why they move that way.
Topic 06H and 2nd Shell Electronegativity
The handful of numbers you're expected to recall cold.
Topic 07The Electromagnetic Spectrum
Radio to gamma — the order, wavelengths, frequencies, real-world examples, and how each interacts with matter.
Topic 08Walking Science Facts
Dr. Laude's ballpark quantities you should know without calculating.
Topic 09Functional Relationships
Direct, inverse, square, log, exponential — read the graph, name the function.
Topic 10Scientific Notation
Write huge and tiny numbers cleanly, then multiply and divide them without panic.
Al says…
Study in short bursts, not marathons. Fifteen minutes a night with flash cards will beat a three-hour panic session the day before the test — every single time.
