Helium Element Cube Historical Artifacts This tier features our substantialHelium's atomic number is 2 and its symbol is He. Helium is the first noble gas and is colorless, tasteless, odorless, and non toxic. Helium has the lowest boiling point of all of the elements. Helium is named after the Greek god of the sun, Helios. This is because the element was first noticed as researchers observed a solar eclipse and noticed the color signature of helium. Despite helium being used to fill party balloons, it is a non renewable
