One of the first people to state that matter is made up of atoms was Democritus.
The idea that matter is made up of atoms was proposed by the ancient Greek philosopher Democritus around 400 BCE. He believed that all matter consists of tiny, indivisible particles called atoms.
The fourth state of matter is plasma, which is a highly energized state in which atoms are stripped of their electrons. The fifth state of matter is Bose-Einstein condensate, which occurs at very low temperatures close to absolute zero, causing atoms to clump together and behave as a single quantum entity.
The atoms of a gas have more energy than the atoms in a liquid or solid state of matter. In a gas, the atoms are moving around freely and have higher kinetic energy compared to the more constrained motion of atoms in a liquid or solid.
When atoms gain enough energy to be able to move freely and independently, the matter has changed into the state of a gas. In the gas state, atoms are not fixed in a specific position and can move and interact with other atoms more freely compared to in solid or liquid states.
You suppose reality is made up of individual bits of "matter" called "atoms"? And that these things can not exist in of themselves (free state)? The more powerful question you should be asking is, "why do scientists believe matter can be created and/or destroyed", when that violates their own laws of thermodynamics that state matter can not be created and/or destroyed? You also need to ask, "why do we still believe in matter/atom concept?", when it is clear mainstream mathematical physics has made the concept of matter/atom too complex to understand?
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.
atoms
solid state
Solid !
Gas ...
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.
solid state
Atoms are related to elements because atoms are what comprise elements. An atom still has atoms no matter what state it is in.
Solid.
