Period Number of Lanthanum (La) (& Location, Uses ... 2022

All atoms have a period number assigned, even Lanthanum. Ok but how do we know what is the period name for an atom of La?

If we know the symbol, let's say La, we may then open any periodic table and search for Lanthanum. Any decent periodic table should have the period numbers when you scroll left starting from the element you found.

In the case of Lanthanum the period number is 6. There is a lot of cool stuff about Lanthanum that people simply don't know. Let me show you...
