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 2s² 2p⁶ represent?

Back

It represents the electron configuration of an atom, showing the number of electrons in each subshell.

Front

How many electrons can the s sublevel hold?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

How many electrons can the p sublevel hold?

Back

The p sublevel can hold a maximum of 6 electrons.

Front

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

Back

The d sublevel can hold a maximum of 10 electrons.

Front

What is the electron configuration for Zinc (Zn)?

Back

The electron configuration for Zinc is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰.

Front

Which element has the electron configuration 1s² 2s² 2p⁶ 3s² 3p¹?

Back

The element is Aluminum (Al).

Front

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

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
