You started this series with one atom. Hydrogen. One proton, one electron, 75 percent of everything that exists. Nine articles later, you've built from that single element outward — through the periodic table, through element personalities, through bonds, reactions, acids, the mole, organic chemistry, and energy. Each piece layered

Every chemical reaction involves energy. Every single one. The match that lights, the food that digests, the battery that drains, the ice that melts, the plant that grows. Energy is not a side topic in chemistry. It's the driving force behind every reaction you've studied in

There are about 118 known elements. One of them — carbon — has so many compounds that it gets an entire branch of chemistry to itself. Organic chemistry. A whole field, a whole course in college, a whole industry of textbooks and tutors and terrified pre-med students. All because of one element

6.022 x 10^23. That's Avogadro's number. It's the number of particles in a "mole" of any substance. Your teacher probably wrote it on the board and told you to memorize it. You probably looked at it and wondered why anyone

You've been doing acid-base chemistry your entire life. You just didn't have the vocabulary for it. When you squeeze lemon juice on fish to cut the smell, you're using an acid to neutralize amine bases. When you take an antacid for heartburn, you'
