A battlefield. Reactants on the left, products on the right. A tiny general shouting: “WHAT YOU START WITH, YOU END WITH!” Conservation of mass. You can’t create or destroy atoms—just rearrange them. Alex had written: “Coefficients are your friends. Subscripts are lies (don’t change them).”

As the night wore on, Alex stopped panicking. His messy, sarcastic, ridiculous notes weren’t a textbook. They were his brain on paper—flawed, funny, but deeply personal. Each bad drawing and angry scribble unlocked a memory of the lesson: the teacher’s offhand joke, the lab where he’d nearly set his sleeve on fire, the study group where someone finally explained why water expands when it freezes (hydrogen bonding—page 31, doodle of a water molecule doing yoga). chemistry year 11 notes

Alex had drawn two stick figures: a metal (sweating, holding a sign that said “+”) and a non-metal (smug, holding “-”). The caption read: “They fight until they attract. Then they become a compound—and chill.” Suddenly, Alex remembered: metals lose electrons (become cations, positive), non-metals gain (anions, negative). Opposites attract. Table salt isn’t magic; it’s just sodium and chlorine finishing each other’s… electron shells. A battlefield
