Valence Electrons in Hassium (Hs)

Valence Electrons in Hassium

Determine the number of valence electrons in Hassium (Hs, Element 108)

Step 1: Look up the electronic configuration for Hassium

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

[Rn] 5f¹⁴ 6d⁶ 7s²

Calculate Electronic Configuration for Hassium

Step 2: Identify the outermost electrons using the electronic configuration

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

5f¹⁴ 6d⁶ 7s²

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:

The outermost electrons with the largest principal quantum number (in this case, n = 7) are valence electrons.

Answer

Hassium (Hs) has 2 valence electron(s).
