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 3) choose all that apply. choose two scientists whose discoveries helped form the cloud model of an atom. schrödinger bohr heisenberg dalton

Explanation:

• For statement 1: Schrödinger developed the Schrödinger equation which is used to understand energy levels in an atom.
• For statement 2: Heisenberg developed the uncertainty principle.
• For statement 3: de Broglie proposed the wave - particle duality of matter.
• For question 3: The cloud model of the atom was formed using contributions from Schrödinger (through his wave equation which describes the probability of finding an electron in a region) and Heisenberg (uncertainty principle which implies that we cannot know the exact position and momentum of an electron simultaneously, leading to the idea of an electron cloud).

Answer:

2)

• "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. Schrödinger, Heisenberg
