Hey, don’t hard out your self for learning the whole periodic table. Because you don’t need to. You are only expected to remember the first 30 elements on your periodic table. Your school will never ask you to remember the whole Periodic table and there is a big theory behind the Periodic table. It will be not even until Year11.
