Question

which scientist developed the quantum mechanical model of the atom?
albert einstein
ernest rutherford
niels bohr
erwin schrodinger

Explanation:

• Albert Einstein: Known for the theory of relativity (special and general), not the quantum mechanical model of the atom.
• Ernest Rutherford: Proposed the nuclear model of the atom (a dense nucleus with electrons around it), not the quantum - mechanical model.
• Niels Bohr: Developed the Bohr model (semiclassical, with electrons in fixed orbits), not the full quantum mechanical model.
• Erwin Schrödinger: Developed the quantum mechanical model of the atom using wave functions and the Schrödinger equation.

Answer:

Erwin Schrödinger
