gaseous state
Helium is a chemical element that exists in a gaseous state at room temperature and pressure. It is one of the few elements that remains a gas under normal conditions, even at very low temperatures.
The standard state of magnesium is solid.
helium is in the family of noble gases according to the periodic table
Hydrogen has atomic number 1 whereas helium's is 2.
The standard heat of formation of a free element in its standard state is defined as zero. This is because it is the reference point from which the heat of formation of other compounds is determined.

Helium is a gas at room temperature.
heliums period address is 11.09
The Heliums period is a explosive force of matter which produces nano bits of helium. The shockwave contributes to events here on Earth. Scientists are still trying to decode the main details.
helium doesn't have a specific gravity
helium has only one energy level (with 2 electrons in it).
