Dalton's atomic model sets up the building blocks for others to improve on. Though some of his conclusions were incorrect, his contributions were vital. He defined an atom as the smallest indivisible particle.

Dalton proposed his atomic theory in 1804. The general tenets of this theory are: All matter is composed of extremely small particles called atoms; Atoms cannot be subdivided, created, or destroyed. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
Atoms are mostly empty space. Thus, a “nucleus” is positive & Negative electrons orbit a positive nucleus. • Electrons orbit the nucleus in “shells” Electrons can be bumped up to a higher shell if hit by an electron or a photon of light. There are 2 types of spectra: continuous spectra & line spectra.
Describe the history of the atom. Draw a diagram of a model of the atom and label the nucleus and the electron cloud. The history of the atom begins before 1800, where an atom was thought to be the smallest piece of matter. The first scientist to provide a theory about the atom was John Dalton.
