A
$[\mathrm{Xe}] 4 f^{14} 5 d^{10} 6 s^2$
B
$[\mathrm{Xe}] 4 f^{14} 5 d^9 6 s^2$
Correct answer
C
$[\mathrm{Xe}] 4 f^{14} 5 d^{10} 6 s^1$
D
$[X e] 4 f^{14} 5 d^9 6 s^1$

Solution

The electronic configuration of the element $\mathrm{Au}$ is [Xe] $4 f^{14} 5 d^{10} 6 s^1$

Hence, the correct answer is option: 'C'.
