Thulium is an lanthanide element with atomic number 69.
Uranium is a member of the actinides (or actinoids) family; no other number.
Uranium is not the largest in the actinoids family but also not the smallest.
Uranium-238 is a member of the actinide family of elements. It is a heavy, radioactive metal that is part of the actinide series, which includes elements with atomic numbers from 89 (actinium) to 103 (lawrencium).
D. Promethium (Pm) is the element in the lanthanide family. The lanthanides, also known as the rare earth elements, consist of 15 elements from lanthanum (La) to lutetium (Lu). Gold (Au), silver (Ag), and uranium (U) do not belong to this group.
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
