When did Niels Bohr formulate his atomic model?

Answer 1

Schrödinger's wave equation was based on the Heisenberg uncertainty principal that the position and velocity of a electron cannot be determined accurately (accuracy in one will sacrifice accuracy in another). Schrödinger's wave equation gave a wave function, which squared gave the probability cloud of electrons. Therefore, Schrödinger's contribution resulted in the electron cloud model of the atom.

Answer 2

Neither Schrödinger nor anybody else "invented" the atom; it was "discovered", not invented. The knowledge of the atom increased gradually; this was not a single year. Schrödinger was just one of many who contributed to the knowledge about it.

Answer 3

He first put his atomic model forward in 1926.

Answer 4

Bohr first publicly stated his postulates in three papers published in Philosophical Magazine in the second half of 1913.

Answer 5

Atomic theory:

* Leucippus (approx. 500 BC) and Democritus (approx. 460-370 BC)

* John Dalton - 1819

* Twentieth century; Bohr, Rutherford, etc.

Answer 6

1926
