Which is lighter oxygen helium or nitrogen?
Helium
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
What element has the least protons of mercury helium uranium nitrogen?
Helium, with only two protons per atom. In contrast, nitrogen has 7, mercury has 80, and uranium has 92.
What impurities are found in helium?
This depends on the preparation method and the quality of helium; generally traces of oxygen, nitrogen other noble gases.
Why do you use helium to super-cool magnets and why not use liquid nitrogen?
Liquid nitrogen is not cold enough to supercool some superconducting magnets to make that magnet's superconductive properties emerge. It takes something like liquid helium to do that.
Why is there nitrogen in helium?
Um... because the helium was insufficiently purified? There is no nitrogen in pure helium.
What is the chemical formulas for helium and nitrogen?
Helium is He Nitrogen is N2
Is nitrogen and helium a hot gas?
yes helium and nitrogen are hot gases
Which is lighter oxygen helium or nitrogen?

Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
