Chemistry Chapter 9

These men played a role in the development of quantum mechanics. They were astonished by their own theories.

These models explain how electrons exist in atoms and how those electrons exist in atoms and how those electrons affect the chemical and physical properties of elements.

Light is a form of this

The constant speed of light is...

The ___________ is defined as the distance between adjacent wave crests.

The number of cycles or crest that pass through a stationary point in one second is known as.....

A unit of light is called a...

The entire range of the electromagnetic radiation is called the....

The relationship between wavelength and frequency is....

__________ have the shortest wavelength and  the high energy and frequency

Next on the spectrum with longer wavelengths and lower energy than Gamma rays are....

Between X-Rays and visible light, and a component of the sunlight is...

ranging from violet(short wavelength w/higher energy to red(with long wavelengths w/low energy)

All warm objects emit this form of light For example, human bodies. Its next to visible light on the spectrum but invisible to our eyes.

Even longer wavelengths then the ladder, these are often used in radar.

The longest wavelengths with the lowest energy. Used in television and communication systems

When an atom absorbs energy an electron in one of the orbits is...

When the atom has undergone excitation it becomes less stable and the electron falls back or....
