Calculate the number of valence electrons in Seaborgium using its electron configuration step by step.
Determine the number of valence electrons in Seaborgium (Sg, Element 106)
The abbreviated (condensed) ground electronic configuration for Seaborgium is:
[Rn] 5f14 6d4 7s2
Calculate Electronic Configuration for Seaborgium
Electrons in atomic orbitals outside the [Rn] core are the outermost electrons:
5f14 6d4 7s2
Extract the principle quantum number, n, and number of electrons from the electron configuration:
Electron Configuration | n | Orbital | Number of Electrons |
---|---|---|---|
5f14 | 5 | f | 14 |
6d4 | 6 | d | 4 |
7s2 | 7 | s | 2 |
The outermost electrons with the largest principal quantum number (in this case, n = 7) are valence electrons.
Seaborgium (Sg) has 2 valence electron(s).
