bobo, sidsen, Gammafunction and nisha’s thambi got the theme! 1 point for the answer + 2 points for the theme added to their totals :-)

Answer:
Models of the atom and how they evolved through the years:
1) John Dalton’s atomic theory
2) JJ Thompson’s plum-pudding model of the atom
3) Rutherfords model of the atom, from the gold-sheet experiment
4) Bohr’s model of the atom (discrete electron orbits!)
5) Current model of the atom with the concept of electron clouds around a nucleus, based on Heisenberg’s theories.

The answer: Bohr’s model of the atom.
