Describe the key findings of Rutherford's Gold Foil Experiment and how they led to the nuclear model of the atom.

Most alpha particles passed through the foil, suggesting atoms are mostly empty space with a small, dense nucleus.

Alpha particles were deflected by electrons, indicating a dense electron cloud.

Alpha particles were absorbed by the foil, suggesting atoms are solid.

Alpha particles created new elements upon impact, indicating transmutation.

Compare and contrast the Bohr Model with the Quantum Atomic Model in terms of electron behavior and energy levels.

Both models describe electrons in fixed orbits.

The Bohr Model describes electrons in fixed orbits, while the Quantum Model describes electrons in probabilistic orbitals.

Using Heisenberg's Uncertainty Principle, explain why it is impossible to know both the position and momentum of an electron simultaneously with absolute precision.

Because electrons are too small to be observed.

Because measuring one property affects the other.

Because electrons do not have a definite position.

Because electrons are always in motion.

Analyze the limitations of the Bohr Model and how the Quantum Atomic Model addresses these limitations.

The Bohr Model could not explain the spectra of larger atoms; the Quantum Model uses orbitals to explain electron behavior.

The Bohr Model could explain all atomic spectra; the Quantum Model could not.

The Bohr Model used probabilistic orbitals; the Quantum Model uses fixed orbits.

The Bohr Model was more accurate than the Quantum Model.
