Enter the atomic number or symbol of any element, and this calculator will calculate its valence electrons with steps.

Valence Electrons in Gold

Determine the number of valence electrons in Gold (Au, Element 79)

Step 1: Look up the electronic configuration for Gold

The abbreviated (condensed) ground electronic configuration for Gold is:

[Xe] 4f14 5d10 6s1

Calculate Electronic Configuration for Gold

Step 2: Identify the outermost electrons using the electronic configuration

Electrons in atomic orbitals outside the [Xe] core are the outermost electrons:

4f14 5d10 6s1

Step 3: Use the principle quantum number to identify the valence electrons

Extract the principle quantum number, n, and number of electrons from the electron configuration:

Electron ConfigurationnOrbitalNumber of Electrons

The outermost electrons with the largest principal quantum number (in this case, n = 6) are valence electrons.


Gold (Au) has 1 valence electron(s).
