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

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

In the case of Helium the period number is 1. There is a lot of cool stuff about Helium that people simply don't know. Let me show you...
