I am on a roll with these practices! My best is 52, how good are you? You have 2 minutes to get as many as you can. Try my polyatomic ions quiz if you dare! https://scratch.mit.edu/projects/934898468/ Tell me if you want a practice game for you! Note: This quiz has prefixes from 1-10. If you want to add more prefixes yourself, just add the prefix to the prefixes list in the code in "setup." By the way, I am starting a new account! @GreeneBolt ! I will probably post occasional mini projects or "work in progress" projects on this account, but all of my new games will be located in my GreeneBolt account.
