Ionic BondingElectrons handed over, not shared — and the properties that follow.Covalent BondingElectrons shared between two non-metals, and why the properties are so different.Balancing EquationsConservation of mass, enforced with coefficients — never with subscripts.The Five Reaction TypesRecognising the pattern tells you what the products will be.Acids and BasesThe pH scale, what it measures, and the reaction that cancels both.The Gas LawsThree relationships between pressure, volume and temperature.Bonding & ReactionsIonic vs covalent bonding, valence electrons and the five reaction types.Electron ConfigurationWhere the electrons actually sit, and why the periodic table is shaped as it is.Why the Trends HappenTwo competing forces explain every periodic trend.Limiting ReactantsWhich ingredient runs out first, and why that decides the yield.Energy in ReactionsExothermic and endothermic, and the bond-energy explanation.
