What is the electron configuration for mercury and its plus 2 ion?

Answer 1

Mercury has the atomic number of 80 with the orbital configuration of [Xe] 4f14 5d10 6s2. With a net charge of 2+, there are two fewer electrons, leaving the configuration of [Xe] 4f14 5d10.

Answer 2

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10. Then for the plus 2ion it's the same thing except for at the end it's not 5d10 it's 5d8

Answer 3

The electron configuration for mercury is [Xe] 4f14 5d10 6s2. When mercury forms a +2 ion, it loses two electrons from its 6s orbital, resulting in an electron configuration of [Xe] 4f14 5d10.
