Modern Atomic Theory Flashcard 1

Front

What property of the electron is used to model the atom in the modern atomic theory?

Back

The electron is a particle that can behave as a wave.

Front

What causes the phenomena of colors?

Back

The phenomena of colors is caused by the absorption and emission of light energy by electrons as they move away and towards the nucleus.

Front

Which part of the atom is responsible for absorbing or releasing energy?

Back

Electron.

Front

What is the modern atomic theory?

Back

The modern atomic theory describes atoms as having a nucleus surrounded by electrons that exhibit both particle and wave-like properties.

Front

Define electron configuration.

Back

Electron configuration is the distribution of electrons in an atom's orbitals.

Front

What is the significance of the quantum mechanical model of the atom?

Back

The quantum mechanical model describes the behavior of electrons in atoms and incorporates the principles of wave-particle duality.

Front

What is the principle of wave-particle duality?

Back

Wave-particle duality is the concept that particles, such as electrons, exhibit both wave-like and particle-like properties.

Front

What is an atomic orbital?

Back

An atomic orbital is a region in an atom where there is a high probability of finding an electron.

Front

What is the role of photons in atomic energy transitions?

Back

Photons are particles of light that are emitted or absorbed when electrons transition between energy levels in an atom.

Front

Explain the concept of energy levels in an atom.

Back

Energy levels are the fixed distances from the nucleus where electrons can exist, each associated with a specific amount of energy.
