Who proposed the atom theory that all matter is composed of atoms and that all atoms of an element are alike?
John Dalton proposed the atom theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that all atoms of a specific element are identical in size, mass, and properties.
All elements are composed of extremely small particles called?
Fermion
What things in a classroom are made of atoms?

What two things make up matter?

Is matter made of molecuesnot atoms?
Most matter doesn't exist as individual atoms. Inert or "noble" gasses like helium and argon excepted, most matter exists in molecules that are composed of two or more atoms. Even pure oxygen isn't individual atoms; oxygen is the O2 molecule composed of TWO oxygen atoms. Except within the cores of stars, hydrogen, the most common element, normally exists as the H2 hydrogen molecule. So in general, matter is composed of molecules, which are composed of atoms.

Matter is composed of?
Matter is composed of atoms, which are the basic units of matter. Atoms are made up of protons, neutrons, and electrons. The way these atoms are arranged and interact with each other determines the properties of different types of matter.
What states that matter is composed of atoms?
The ATOMIC THEORY states that all matter is composed of very small particles called atoms, and that those atoms cannot be broken apart.
