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.
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

.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
The electron configuration of thaliium III ion is [XE] 4f14 5d10.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
hafnium
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
Al+3 aluminum
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
The electron configuration of thaliium III ion is [XE] 4f14 5d10.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
Al3+
Al3+
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
