BELL-RINGER: Electron Configuration

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

What does the notation 1s² represent?

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

What is the maximum number of electrons that can occupy a p orbital?

Back

6 electrons.

Front

What is the maximum number of electrons that an s orbital can have?

Back

2 electrons.

Front

What is the electron configuration for Chlorine (Cl)?

Back

1s² 2s² 2p⁶ 3s² 3p⁵.

Front

How many total electrons are in a neutral atom of Magnesium (Mg)?

Back

12 electrons.

Front

What is the electron configuration for Zinc (Zn)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

It states that electrons fill orbitals starting from the lowest energy level to the highest.

Front

What is Hund's rule?

Back

Electrons will occupy degenerate orbitals singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.
