Proposed the “plum pudding” model of the atom.

• Dalton

• Thomson

• Rutherford

• Bohr

Explain Dalton's atomic theory.

• Atoms of the same element can have different properties

• All matter is made up of energy, not particles

• Atoms can be divided into smaller particles

• All matter is made up of tiny, indivisible particles called atoms, and atoms of the same element are identical in size, mass, and other properties.

What was Thomson's plum pudding model?

• Protons embedded in a negatively charged sphere

• Electrons embedded in a positively charged sphere

• Electrons orbiting around a nucleus

• Neutrons embedded in a neutrally charged sphere

Who propoesed that electrons move around a central nucleus?

• Dalton

• Thomson

• Rutherford

• Bohr

Electrons do not have definite orbits, but are described by wave functions that represent probability distributions of their locations.

• Schrödinger

• Thomson

• Rutherford

• Bohr
