Unit 04 Review - Electrons - 1 Light and Atoms - 531/532

Front

What happens to light energy when an atom undergoes an energy change?

Back

It can be absorbed.

Front

Which property of light does not change when the other properties change?

Back

Luminous intensity.

Front

Why must an atom absorb energy to move an electron farther from the nucleus?

Back

Electrons are attracted to the nucleus.

Front

What does it mean for energy levels in an atom to be quantized?

Back

Energy levels are fixed and discrete, not continuous.

Front

Which transition between energy levels in an atom releases the highest energy?

Back

From n=4 to n=1.

Front

Define 'electron.'

Back

A subatomic particle with a negative charge that orbits the nucleus of an atom.

Front

What is the relationship between wavelength and energy of light?

Back

Shorter wavelengths correspond to higher energy.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation.

Front

What is the principle of quantization in atomic physics?

Back

Energy levels in an atom can only take on specific values.
