Electron Configuration Part 2

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating how electrons are arranged around the nucleus.

Front

What is the significance of the noble gas in shorthand electron configuration?

Back

Noble gases have full valence shells, making them stable. In shorthand notation, the electron configuration of the nearest noble gas is used to simplify the representation of an element's electron configuration.

What is the electron configuration for Chlorine (Cl)?

Back

The electron configuration for Chlorine (Cl) is [Ne] 3s² 3p⁵.

Front

What is the electron configuration for Argon (Ar)?

Back

The electron configuration for Argon (Ar) is 1s² 2s² 2p⁶ 3s² 3p⁶.

Front

What is the shorthand electron configuration for Calcium (Ca)?

Back

The shorthand electron configuration for Calcium (Ca) is [Ar] 4s².

Front

What is the electron configuration for Sulfur (S)?

Back

The electron configuration for Sulfur (S) is [Ne] 3s² 3p⁴.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons is determined by the group number of the element in the periodic table. For main group elements, the group number corresponds to the number of valence electrons.

Front

What element in Period 5 has 1 valence electron?

Back

Rubidium (Rb) has 1 valence electron in Period 5.

Front

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

Back

The maximum number of electrons that can occupy the s orbital is 2.

Front

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

Back

The maximum number of electrons that can occupy the p orbital is 6.
