The chemical symbol for helium is "He."
What is colder helium or hydrogen?

Why helium is used in weather balloons rather than hydrogen?
Because of an accident that happened. A weather balloon was filled with hydrogen and when lightning hit it, it set on fire. Hydrogen is flammable, so they use Helium instead, because Helium is a nobel gas and so isn't flammable, but also lighter than air so the balloon floats.

what is Helium about?
helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium.
