The Ultimate Quiz On Chemistry For 10th Grade

The word atom comes from the ancient Greek word atomos meaning unsplittableor uncuttable. A philospher called Democrites carried out a thought experiment. He imagined taking a piece of rock and hitting it with a hammer. That's enough history, let's do Chemistry!
