Valence Electrons in Polonium

Determine the number of valence electrons in Polonium (Po, Element 84)

Step 1: Look up the electronic configuration for Polonium

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

[Xe] 4f14 5d10 6s2 6p4

Calculate Electronic Configuration for Polonium

Step 2: Identify the outermost electrons using the electronic configuration

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

4f14 5d10 6s2 6p4

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.


Polonium (Po) has 6 (2 + 4) valence electrons.
