Electron Configuration and Aufbau Diagram

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 Aufbau principle state?

Back

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

Front

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

Back

2 electrons.

Front

How many orbitals are in the p sublevel?

Back

3 orbitals.

Front

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

Back

6 electrons.

Front

What is Hund's rule?

Back

Electrons will fill 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; thus, an orbital can hold a maximum of two electrons with opposite spins.

Front

What is the electron configuration for Neon (Ne)?

Back

1s² 2s² 2p⁶.

Front

What is the significance of the Lewis dot diagram?

Back

It represents the valence electrons of an atom and helps in understanding bonding and molecular structure.

Front

How many valence electrons does Carbon have?

Back

4 valence electrons.
