What is the shorthand electron configuration of Au?
What is the shorthand electron configuration of Au?
1 Answer
Askiitians Tutor Team
The shorthand electron configuration of an element is typically represented using the noble gas configuration as a starting point. For gold (Au), the noble gas that comes before it in the periodic table is Xenon (Xe), which has the electron configuration:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰
To represent the electron configuration of gold (Au), you can use [Xe] as the shorthand notation, followed by the remaining electron configuration for gold:
[Au] = [Xe] 4f¹⁴ 5d¹⁰ 6s²
So, the shorthand electron configuration of gold (Au) is "[Xe] 4f¹⁴ 5d¹⁰ 6s²."
