Electron Configuration Test Review

Front

What are valence electrons?

Back

The number of electrons in the outermost shell of an atom.

Front

What atom matches this electron configuration: 1s² 2s² 2p⁶ 3s²?

Back

Magnesium.

Front

As wavelength increases, what happens to frequency and energy?

Back

Frequency decreases and energy decreases.

Front

How many electrons can the d sublevel (orbital) hold?

Back

10.

Front

Electrons are paired based on their spin directions, clockwise and counterclockwise. What is this electron configuration rule?

Back

Pauli Exclusion Principle.

Front

What is the Aufbau Principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's Rule?

Back

Electrons will fill degenerate orbitals singly before pairing up.

Front

What is the maximum number of electrons in the s sublevel?

Back

2.

Front

What is the maximum number of electrons in the p sublevel?

Back

6.

Front

What is the relationship between energy, frequency, and wavelength?

Back

Energy is directly proportional to frequency and inversely proportional to wavelength.
