Chemistry revision · 24 cards
Understand it first, then test yourself. Work through the labs in order, then use the flashcards to check what's stuck.
Start here: protons, neutrons and electrons, filling the shells, the periodic table, and how atoms become ions.
How atoms hold together: the electron sea in metals, plus the small molecules H2, O2, H2O and CO2.
Ionic compounds, soluble vs insoluble, and ions swapping partners to make a solid.
Why ice melts at 0 °C but salt needs 800 °C, what conducts and why, and the giant networks in diamond and graphite.
Why mass is conserved, counting atoms in a formula, balancing equations, and which reactant runs out first.
Metals with acids, water and oxygen. How the product gets its name, and the acid formulas.
Acid + base → salt + water, drop by drop: watch the pH, predict the salt, and test the gas from carbonates.
Complete and incomplete combustion, and why the flame turns from blue to yellow.
Collision theory: how temperature, concentration, surface area and catalysts change how fast a reaction goes.
All 24 cards. Mark the ones you miss and they come back until you've got them.
Each lab ends with a quiz using examples that aren't on the sheet. If you can answer those, you understand the rule rather than just remembering the card.
