Calculate the number of valence electrons in Gold using its electron configuration step by step.
Determine the number of valence electrons in Gold (Au, Element 79)
The abbreviated (condensed) ground electronic configuration for Gold is:
[Xe] 4f14 5d10 6s1
Electrons in atomic orbitals outside the [Xe] core are the outermost electrons:
4f14 5d10 6s1
Extract the principle quantum number, n, and number of electrons from the electron configuration:
|Electron Configuration||n||Orbital||Number of Electrons|
The outermost electrons with the largest principal quantum number (in this case, n = 6) are valence electrons.
Gold (Au) has 1 valence electron(s).
