The first atomic model was developed and Dalton hypothesized that an atom is a solid sphere and can not be divided
-
Discovering that the electron was the negatively charge part in an atom.
-
shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths
-
made the model that depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus
-
used mathematical equations to describe the likelihood of finding an electron in a certain position.
