Dalton's Atomic Theory
The ATOMIC THEORY states that all matter is composed of very small particles called atoms, and that those atoms cannot be broken apart.
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.
The atomic theory is a scientific theory that states that all matter is composed of individual atoms, which are the smallest units of an element that retain the properties of that element. It also proposes that atoms combine in specific ratios to form compounds.
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.
Several answers. First is atoms, all matter is composed of atoms. But then you can worry about atoms. Best (current) answer is quarks, but if you like string theory them maybe all matter is just "frozen" energy. That would certainly help explain e=mc2.
John Dalton provided the basic theory about the nature of matter.
All matter
That all matters are made up of atoms
Yes, all matter is composed of atoms.
It's Atoms
This theory is known as the Kinetic Molecular Theory. It states that all matter is composed of particles (atoms, molecules, or ions) that are in constant motion. The theory helps explain the behavior of gases, liquids, and solids based on the movement of these particles.
