Atomic Structure Theory Quiz

Niels Bohr proposed the planetary model, where electrons orbit the nucleus in fixed paths.

Protons have a positive charge.

Linus Pauling developed the concept of electron configuration in the early 1930s.

Wavelength is the distance between adjacent peaks of a wave.

Electrons have a negative charge.

Louis de Broglie proposed the wave-particle duality, suggesting that electrons exhibit both wave and particle characteristics.

James Chadwick discovered the neutron in 1932.

The principal quantum number indicates the energy level of an electron in an atom.

The Aufbau Principle dictates that electrons fill orbitals in order of increasing energy.

Hund's Rule states that electrons occupy orbitals singly before doubling up in the same orbital.

The Bohr radius is the average distance from the nucleus to the electron in a hydrogen atom's orbit.

The maximum number of electrons in the third energy level is 18.

The 5f orbital has the highest energy among the given options.

The Heisenberg Uncertainty Principle states the limitations in simultaneously knowing the exact position and momentum of a particle.

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

A Rydberg series is a set of spectral lines corresponding to transitions between two energy levels in an atom.
