Earth
Promethium is the rarest naturally occurring rare earth element in the lanthanide series. It is radioactive and not found in significant quantities in the Earth's crust, making it one of the least abundant elements on Earth.
No, germanium is not a rare earth element. It is a metalloid in group 14 of the periodic table, along with carbon, silicon, and tin. Rare earth elements are a group of elements found in the lanthanide series of the periodic table.
Thulium is an lanthanide element with atomic number 69.
Carbon is not a family name; it is a chemical element that is found in group 14 of the periodic table. It is not part of the rare earth elements series, which are a group of 17 elements in the lanthanide series and actinide series of the periodic table.
An element that sounds like Emily is "Emery," which is a rare earth element. It is part of the lanthanide series and has some similar properties to the element erbium.
Xenon is a noble gas and does not belong to the rare earth element series. The rare earth elements are a group of lanthanide elements, plus scandium and yttrium, that have similar chemical properties. Xenon is located in group 18 of the periodic table.
The chemical element of Europium is part of the lanthanide series. The lanthanide series is comprised of metallic elements, these can be referred to as rare earth elements.
Lutetium is one of the first inner transition series metals, sometimes called "lanthanides" because all of them have chemistry very similar to that of lanthanum, the first member of the series.
