Helium is a gas and will take the shape of the container it is taken
what is helium used for
Of course. What a strange question! It implies that helium may be able to keep in a shape that is not the same as its container and thefore leave a vacuum in parts of the container.
When helium is used to fill a balloon, it expands to fill the space inside the balloon due to its low density. The helium gas takes the shape of the balloon because it moves and distributes evenly throughout the balloon's interior.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.

Atoms are generally spherical in shape.

Helium is one of the elements of the periodic table. Helium in the shape where people can get in contact with it may have traces of other elements in it depending on the level of purity, but it's still mainly just helium and almost nothing else.
Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
The helium would take up the whole space of the classroom because it is a gas. A gas can expand as far as it likes because it has an indefinite shape and volume.
Gases have no definite volume or shape. The air that you breathe, the helium in a balloon, and the neon inside the tube in a neon light are gases.
He - Helium
As the balloon rises, the air pressure outside will decrease, and the balloon skin will deform till the pressure on both sides of the skin is the same. Thus your balloon will inflate in shape, towards the spherical, which is the limiting shape for a simple balloon.
