# What is the electron configuration of an element with atomic number 110?

May 29, 2017

Element 110 is thought to have the electron configuration $\left[R n\right] 5 {f}^{14} 6 {d}^{8} 7 {s}^{2}$

#### Explanation:

Element 110 is Darmstadtium (Ds) named after a town in Germany. Much about it is unknown. It is thought to have the electron configuration:

$D s = \left[R n\right] 5 {f}^{14} 6 {d}^{8} 7 {s}^{2}$

This is using the notation based on increments from the nearest noble gas in this case Radon.

To complete the picture Radon's electron configuration is based on increments from Xenon:

$R n = \left[X e\right] 4 {f}^{14} 5 {d}^{10} 6 {s}^{2} 6 {p}^{6}$

Likewise:

$X e = \left[K r\right] 4 {d}^{10} 5 {s}^{2} 5 {p}^{6}$

$K r = \left[A r\right] 3 {d}^{10} 4 {s}^{2} 4 {p}^{6}$

$A r = \left[N e\right] 3 {s}^{2} 3 {p}^{6}$

$N e = \left[H e\right] 2 {s}^{2} 2 {p}^{6}$

$H e = 1 {s}^{2}$
