This quiz covered atoms and there electrons, protons and neutrons. Along with periodic symbols and there atomic mass and number. On this Chemistry I got a 7/7 which is a meets. I did accidentally press the submit button before I answered two questions but Ms. Issak quized me on them and I got them right so in the end I did get 7/7. Finally for my next quiz I will pay more attention and not press anything before im dont and check my answers.
