No.
Helium is one of the lightest elements in the world and is not commonly used in any form of transportation. To answer your question the compound used to lift rockets is liquid oxygen.

Expand and lift off into space.
It Starts up and then it take off as a usually rockets will do
Newton's third law, for every action there is an equal and opposite reaction.
Rockets take off to carry things (called payloads) into space. Do you mean 'how' do rockets take off, or how do rockets work?
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
Depends on the weight. Check the MythBusters website, they did an experiment on this.
Yes it does. The more weight that there is in the rocket, the more energy it takes to lift off. Its the same as if you raised your hand above your head and it's empty. Put a ten pound weight in it and you have to exert more energy to lift it.
Atoms of Helium !
Because it's too heavy ! It would take much bigger and more powerful rockets to lift a craft made of iron off the launch-pad.
yes if you can try googling lifter or search it on youtube its a way where pretty much electrons are shot out of it and lift off the ground kind of like rockets on a space shuttle
Two huge solid fuel rockets, and Three big rocket motors burning fuel from an external tank big as a grain silo at a ferocious rate.
