Chemistry Chapter 4 Review

Electromagnetic Radiation

100

The distance between two points on adjacent waves.

What is Wavelength?

200

This is emitted when an electron moves from an excited state to the ground state.

What is a photon?

OR

What is energy?

300

The spectrum that lists all electromagnetic energy in order of their energies.

What is the electromagnetic spectrum?

400

The quantity represented by v that measures how many times a wave passes through one point per second.

What is frequency?

500

The phenomenon that occurs when electromagnetic radiation strikes the surface of a metal and that metal ejects electrons.

What is the photoelectric effect?

Quantum Numbers

100

The quantum number with two possible values (positive and negative)

What is spin?

200

The quantum number that represents the main energy level of an electron.

What is the principal quantum number, n?

300

The quantum number that represents the shape of an orbital.

What is the angular momentum quantum number?

400

If an orbital has two electrons in it, they must have opposite _____________.

What are spin states?

500

An electron in the 3s sublevel has this main energy level value. 

What is 3?

Electron Configurations

100

Each arrow in orbital notation represents one of these. 

What is an electron?

200

The amount of electrons (arrows) allowed on each "line" (orbital) in orbital notation.

What is 2?

300

The amount of electrons in sublevel 3p⁴.

What is 4?

400

5 electrons in a 3d sublevel.

What is 3d⁵

500

The electron configuration for Carbon, which has 6 electrons.

What is 1s² 2s² 2p²

Energy

100

The state where an electron has the lowest possible energy. 

What is the ground state?

200

What is emitted from an electron when it moves from an excited state to the ground state. 

What is energy or light or electromagnetic radiation?

300

The equation that we use to find wavelength or frequency of a light wave.

What is v = _/\  x c ?

or 

What is frequency = wavelength x speed of light?

400

This is increased as an electron moves away from the nucleus and decreased as an electron moves closer to the nucleus.

What is energy?

500

This is distance is smaller when frequency and energy of a wave are higher. 

What is wavelength?

Orbitals

100

This is the possible number of orientations an s orbital can have.

What is one?

200

This rule states that each orbital must have one electron before any orbital receives a second.

What is Hund's rule?

300

This is all the possible places an electron can exist around the nucleus.

What is an orbital?

400

The number 2 represents this in the orbital 2p¹

What is the principal quantum number or the main energy level.

500

The number of electrons in a 2p¹ orbital.

What is 1 electron in a p shaped orbital?
