Please organize the models of the atom, by creator, in chronological order with the first model at the top and the most recent model at the bottom of the list.

  1. Erwin Schroedinger

  2. Ernest Rutherford

  3. John Dalton

Please organize the models of the atom, by description, in chronological order with the first model at the top and the most recent model at the bottom of the list.

  1. Solid, uniform sphere

  2. Solid sphere with negative particles dispersed throughout a positively-charged material

  3. Empty sphere with a small, dense nucleus and electrons in the mostly-empty region around the nucleus

  4. Empty sphere with electrons organized in specific energy levels orbiting the nucleus

Please organize the models of the atom, by key discovery, in chronological order with the first model at the top and the most recent model at the bottom of the list.

  1. Atoms combine in specific, whole-number ratios

  2. Most alpha radiation can travel through a thin sheet of gold foil, but a few will bounce back at acute angles as if being deflected by something

  3. Each element emits only some specific colors, never the full rainbow

  4. Every metal has small, negative particles that can flow out of the atom when they are given enough energy

  1. Central nucleus

  2. Organized electrons

  3. Solid, uniform sphere

  4. Raisin Bun Model

  5. Cloud (or wave) model [picture of cotton candy]
