MODELS
Nuclear model – dense, positive nucleus surrounded by negate electrons
Planetary Model electrons of atoms are limited to a certain circular orbit around the nucleus. Similarly to the planets orbiting the Sun.
Plum pudding model a positive charge sphere with a few negatively charged particles, scattered in the sphere like raisins.
Neutron model atoms had their mass and positive electric charge concentrated in a very small nucleus.
Wave Model/Quantum Mechanical Model demonstrates that electrons are just as much a wave of energy as they are particles.
Solid Sphere Model a solid, indivisible sphere. Unable to destroy or reconstruct.
