11 Notes — Chemistry Year

“Right,” Alex muttered. “This is useless.”

A thermometer crying ice cubes (endothermic: absorbs heat, feels cold) and a thermometer on fire (exothermic: releases heat, feels hot). His caption: “Endo = enters cold. Exo = exits hot.” Simple. He’d never forget that now.

This page was a crime scene. Crossed-out numbers, tear stains, and a furious scribble: “WHY IS AVOGADRO’S NUMBER 6.02 x 10^23???” Below, in smaller handwriting: “Because it’s the number of particles in one mole. Just memorize it, idiot.” Alex laughed. He’d written that. And now he remembered: moles = mass / molar mass. n = m/M. The formula had clawed itself into his brain through sheer frustration. chemistry year 11 notes

By 2 a.m., Alex closed the notebook. He didn’t know every formula perfectly. But he knew the story of year 11 chemistry: the drama of electrons, the tension of bonds, the absurdity of measuring atoms in moles because numbers got too big.

And he never threw away those notes. Because year 11 chemistry wasn’t just a subject—it was the first time he realized that even the messiest, most chaotic version of learning could still be exactly what you needed. “Right,” Alex muttered

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).”

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. Exo = exits hot

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).
