Positive - Positive charges in the centre
Negative - No Nucleus
Ernst Rutherford - Nuclear Model -Discovered the Nucleus and the atoms are mostly empty space
Positive - Positive charges in the center
Negative - No explanation for electron orbits
Neils Bohr - Planetary Model - Electrons orbited the Nucleus in fixed orbits of differing energy level
Positive - Stable electron orbits with emission spectra
Negative - Doesn't work for heavier elements
Erwin Schrodinger - Quantum Model - Electrons don't move in fixed orbits but in waves - Impossible to locate electrons (cloud of possibility)
Positive - Most widely accepted accurate model
