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.
Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...
Helium is an atom. Heavier elements have molecules.
The symbol of Helium is He. Helium's atomic number is 2.
The symbol for hydrogen is H, and the symbol for helium is He.
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
No, helium gas is not a compound. Helium is an element, which means it consists of only one type of atom.
The Latin word for helium is "helium." It is the same in both Latin and English.
Helium is generally used; special spectrometers to detect helium leakage are designed.
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
Helium is an inert gas; only some unstable compounds obtained in very special conditions are known now.
Helium will not bond with anything. Platinum will bond only with fluorine (and under special conditions). So, helium and oxygen will not bond, platinum and silicon will not bond, etc.
What is doubtless the most common use of helium by the elderly is the getting and giving of helium balloons. "Older" people don't do a lot of mixed gas diving, inert gas welding or other activities like that.
