Chemistry Vocabulary

One of the frustrating things that students often find about chemistry is that there are a lot of words that don't make any sense. What the heck are you going to do “stoichiometry” for, and what does it mean if steric hindrance is involved in a reaction? Without some help, all of these things are just random and confusing words.

Fortunately, I've decided to put together a vocabulary list for you that answers these questions of terminology. Most of them, anyway. I've also gone a little nuts with the explanations, so you may find that instead of just getting a definition, you get an entire tutorial. Which isn't really a bad thing, unless you're doing one of those stupid vocabulary lists that teachers sometimes like to assign.

When you click on the links below, you'll find yourself transported to a whole new place of wonder and magic. Or, to put it a little less poetically, you'll find yourself on some pages that have been updated and completed for my website update. The whole site will eventually get that facelift and improvement, but for now, just sit back and enjoy the future... today.
