Please help! I have no idea what a galactic symbol is. It says it on one of my science assignments and I'm confused. All I know is that it may have to do with the periodic table. If anyone could help that'll be great. My assignment is due today and I don't want to fail. (I have no Idea if this is Chemistry or biology. All I know is that its science. So I put Chemistry as the category. I apologize if I'm incorrect.)
