History of atoms

John Dalton

11,803 BCE

This theory proposed almost the same information as Dimocritus the only thing is that he is the 2nd one contributing on the atom theory that needs to be with all the matter was and is composed of atoms.

Modern Quantrum Cloud Model

1930 BCE

This is the theorical basisof modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at the level is sometimes referred to as quantum physics and quantum mechanics.

Bohr atom

1913 BCE

The Bohr model is a planetary model in wich the negatively charged electrons orbt a small, positely charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun.

Rutherford atom

1912 BCE

Ernest rutherf atom is described as a tiny, massive core called the nucleus. The nucleus has positive charge. Electrons are particles with a negative charge. The empty space between the nucleus and the elctrons takes up most of the volume of the atom.

Thomson atom

1897 BCE

The Thomson atom is mainly composed of electrons sorrounded by a soup of positive charge to balance the electrons negative charges, like negatively charged ''plums'' surrounded by positively charged ''pudding'',

Democritus atom

460 BCE

He's theory held that everything composed of "atoms", wich are physically, but not geometrical, indivisable, that atoms are indestructable and there always in motion. Also infinite numbers and kinds of atoms that exist.
