Final Review Questions

Theories of Matter: Dalton: Thomson Thomson proposed the first atomic model, that was described as //a positively-charged sphere in which the electrons were inlaid (with negative charges)//. It is known as the //plum pudding model//.
 * 1) All [|matter] is formed of [|atoms].
 * 2) That [|atoms] are indivisible and invisible particles.
 * 3) That [|atoms] of the same [|element] are of the same class and the same [|mass].
 * 4) The [|atoms] that form compounds are in relation of entire and single numbers; can be of two or more different classes.
 * 5) Chemical changes correspond to a combination by division or reordering of [|atoms] forming part of a chemical reaction.

Rutherford suggested that the positive charges of the [|atom] were found mostly in its center, in the kernel, and the [|electrons] (//e//-) around it.

Bohr had the most modern definition of the atom. With the nucleus in the center and the electrons orbiting around the outside of the atom.
