# What is the abbreviated electron configuration of platinum (Pt)?

Apr 29, 2014

Platinum is located in the transition metals in the 6th period (row of the periodic table.

To write the abbreviated electron configuration we would use the Noble gas Xenon from the 5th period of the table.

$\left[X e\right] 4 {f}^{14} 5 {d}^{9} 6 {s}^{1}$

The the additional electron on the 5d orbital jumps down an energy level from the 6s orbital.
