      To add on James’ answer, Dysprosium is also very useful and has lots of applications, for example hard drives and memory storage. It’s used in lasers and also infra red detectors

      Not in anyway related to the question but the Lanthanides are what I study in my job. They are different to everything else in the periodic table because they exist for different amounts of time and are very radioactive.
