Valence Electrons in Tennessine

Determine the number of valence electrons in Tennessine (Ts, Element 117)

Step 1: Look up the electronic configuration for Tennessine

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

[Rn] 5f14 6d10 7s2 7p5

Calculate Electronic Configuration for Tennessine

Step 2: Identify the outermost electrons using the electronic configuration

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

5f14 6d10 7s2 7p5

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 = 7) are valence electrons.


Tennessine (Ts) has 7 (2 + 5) valence electrons.
