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...
