WHATEVER LAHH CHEM. memorise all those crap atomic numbers for what. its not like its going to be of much importance to anyone if they're not going to become chemists or something. and i doubt chem is useful unless.. you don't want your house to blow up. or get food poisoning. or whatever lahh. I SAY, english is more important. since practically almost the whole world speaks english but nobody speaks chem. SO. THERE. and anyway they're just a bunch of lousy numbers placed in some random order. pfffffffffft.
