Light and the Atomic Model

Front

What is the unit for frequency of electromagnetic radiation?

Back

Hertz

Front

What did Heisenberg state about electrons?

Back

It is impossible to determine simultaneously the position of the electron and its speed.

Front

What is a three-dimensional region around the nucleus where there is a high probability of finding electrons called?

Back

An orbital.

Front

What is the relationship between the speed of light (C), frequency, and wavelength?

Back

C = frequency x wavelength.

Front

What is required for an electron to move from an excited state to a ground state?

Back

Emission of electromagnetic radiation.

Front

Define electromagnetic radiation.

Back

Electromagnetic radiation is a form of energy that travels through space at the speed of light and includes visible light, radio waves, X-rays, and more.

Front

What is the principle of wave-particle duality?

Back

The principle that electrons exhibit both wave-like and particle-like properties.

Front

What is an orbital in atomic theory?

Back

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

Front

What does the term 'quantized' mean in relation to electron energy levels?

Back

Quantized means that electrons can only exist in specific energy levels and not in between.

Front

What is the photoelectric effect?

Back

The photoelectric effect is the emission of electrons from a material when it absorbs light.
