Chemistry: Unit 1.5 Electron Arrangement in Atoms - created from Mind Map_1 As covered briefly in the previous topic, we notice that electrons are arranged in shells around the nucleus. The shells can hold more and more electrons as they get further from the nucleus.the pattern is as follows:... Daena Targaryen
