Gas ...
Atoms of all elements exist in the state of matter known as the gas phase.
This state of matter is the liquid.
The state of matter that keeps atoms together is solid. Liquids and gases allow atoms to break apart from each other.

The first person to state that matter is made up of atoms was the ancient Greek philosopher Democritus in the 5th century BC. He proposed that all matter is composed of indivisible particles called atoms.

Solid !
Spread out.
This question cannot be answered per the Law of Conservation of Matter. It doesn't matter what state a substance is in, it will always have the same atoms and in the same number. A substance that goes from liquid to gas does not "lose" some atoms in the process.
A gas is a state of matter that will spread out to fill up whatever container it is in. Its particles are loosely packed and move freely, taking on the shape of the container.
