Chemistry - Electron Configuration

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² represent?

Back

It indicates that there are 2 electrons in the 1s orbital, which is the lowest energy level.

Front

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

Back

2 electrons.

Front

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

Back

6 electrons.

Front

What is the maximum number of electrons that can occupy a d sublevel?

Back

10 electrons.

Front

What is the noble gas configuration for Neon?

Back

[He] 2s² 2p⁶.

Front

How do you determine the electron configuration of an element?

Back

By following the Aufbau principle, Hund's rule, and the Pauli exclusion principle to fill orbitals in order of increasing energy.

Front

What is the significance of the noble gas configuration?

Back

It provides a shorthand way to represent the electron configuration of an element, highlighting the filled inner shells.

Front

Which element has the electron configuration [Ar] 4s² 3d¹⁰ 4p⁶?

Back

Krypton.

Front

What is the difference between a sublevel and an energy level?

Back

An energy level refers to the main shell of electrons, while a sublevel refers to the specific orbitals within that shell.
