Question

1. drag and drop the scientists with the statements. developed an equation to better understand energy levels in an atom developed the uncertainty principle developed the wave - particle duality of matter choices: schrödinger, de broglie, heisenberg 3) choose all that apply. choose two scientists whose discoveries helped form the cloud model of an atom. dalton, bohr, schrödinger, heisenberg

Explanation:

1. Schrödinger developed an equation for atom energy - levels. Heisenberg developed the uncertainty principle. De Broglie developed the wave - particle duality of matter.
2. Schrödinger's wave equation and Heisenberg's uncertainty principle contributed to the cloud model of the atom.

Answer:

1. developed an equation to better understand energy levels in an atom: Schrödinger

developed the uncertainty principle: Heisenberg
developed the wave - particle duality of matter: de Broglie

1. Choose TWO scientists whose discoveries helped form the cloud model of an atom:

Schrödinger
Heisenberg
