and what would the electron configuration look like? well even if you can only the first question that would help thanks

Cd2+ has 46 electrons. (Normally 48, but two are missing...hence the "2" positive charge) The electron config should be [Kr] 5s^2, 4d^8. Hope this helps.

Correct answer for electron configuration of Cd2+
(Kr) 5s0 4d10
46 total electrons

Basically take the atomic number for cadmium as this will show the number of electrons in comparison with protons, then since you have an overall 2+ chare this means that the atom is looking for two more electrons symbolising that it has lost two electrons already, its electron configuration will be 2,8,18,18 (since it is a transition metal the chells can expand to hold another 10 electrons each.)

Just 46 electrons, because cadmium atomic number is 48, that is 48 electrons when it is not combined, and when is Cd +2 , cadmium lose 2 electrons. Configuration in energy levels is: 2,8 18,18. In orbitals : 1s2,2s2,2p6,3s2,396,3d10,4s2,4p6,4d10

A stable Cadmium molecule has 48 protons and 48 electrons, so an ion with a two plus charge would have two less electrons, giving it a net charge of positive two thanks to the fact that it now has two more protons than electrons. So it would have 46 electrons.

cowdude is almost correct. The configuration of Cd2+ is [Kr]3s0 4d8
