Model of the Atom Timeline
Akira M. Garsed
Hantaro Nagaoka Model of the Atom
- Nagaoka rejected Thomson's model on the grounds that opposite charges are impenetrable. In 1904, Nagaoka proposed an alternative planetary of the atom in which a positively charged center is surrounded by a number of revolving electrons, in the manner of Saturn and its rings.
Ernest Rutherford Model of the Atom
- In many ways, the Rutherford model of the atom is the classic model of the atom, even though it's no longer considered an accurate representation. Rutherford's model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.
Erwin Schrodinger - Electron Cloud Model of the Atom
- The Schrodinger model assumes that the electron is a wave and tries to describe the regions in space, or orbitals, where electrons are most likely to be found. Instead of trying to tell us where the electron is at any time, the Schrodinger model describes the probability that an electron can be found in a given region of space at a given time. This model no longer tells us where the electron is; it only tells us where it might be.
