Answer:

Element 110 is thought to have the electron configuration #[Rn] 5f^(14)6d^8 7s^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:

#Ds=[Rn] 5f^(14)6d^8 7s^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:

#Rn=[Xe] 4f^(14)5d^(10) 6s^2 6p^6#

Likewise:

#Xe=[Kr] 4d^(10)5s^2 5p^6#

#Kr=[Ar] 3d^(10)4s^2 4p^6#

#Ar=[Ne] 3s^2 3p^6#

#Ne=[He] 2s^2 2p^6#

#He=1s^2#
