Bohr
Dalton
Schrödinger

Bohr

Explanation:

Neils Bohr was the scientist that suggested that electrons follow predictable orbits round the nucleus.

In 1913, he put forward his own model of the atom based on the quantum mechanics originally developed by Planck. He assumed the Rutherford's model and suggested that the extranuclear part consists  of electrons in specific spherical orbits around the nucleus. The orbits/energy levels are designated as K, L, M, N
