Electrons in Atoms Lesson 1&2 Review

Front

What are energy sublevels?

Back

Energy sublevels are divisions of principal energy levels in an atom, indicating the relative sizes and energies of atomic orbitals.

Front

What happens to the frequency of a wave when its wavelength decreases?

Back

The frequency of the wave increases.

Front

What is an atomic orbital?

Back

An atomic orbital is a three-dimensional region around the nucleus of an atom that describes an electron’s probable location.

Front

What is amplitude in wave physics?

Back

Amplitude is the wave’s height from the origin to a crest.

Front

What is the quantum mechanical model of the atom?

Back

The quantum mechanical model of the atom treats electrons as waves and incorporates principles of quantum mechanics.

Front

Define principal energy level.

Back

Principal energy levels are the main energy levels of an atom, denoted by quantum numbers, indicating the distance of electrons from the nucleus.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What does the quantum number represent?

Back

Quantum numbers describe the properties of atomic orbitals and the electrons in those orbitals.

Front

What is the significance of the Heisenberg Uncertainty Principle?

Back

The Heisenberg Uncertainty Principle states that it is impossible to know both the position and momentum of an electron simultaneously.

Front

What is the difference between a wave and a particle in the context of electrons?

Back

Electrons exhibit both wave-like and particle-like properties, a concept known as wave-particle duality.
