Valence Electrons in Gadolinium

Determine the number of valence electrons in Gadolinium (Gd, Element 64)

Step 1: Look up the electronic configuration for Gadolinium

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

[Xe] 4f7 5d1 6s2

Calculate Electronic Configuration for Gadolinium

Step 2: Identify the outermost electrons using the electronic configuration

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

4f7 5d1 6s2

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.


Gadolinium (Gd) has 2 valence electron(s).
