Problem 2.47

Postby 604807557 » Wed Jul 12, 2017 7:21 am

For each of the following ground-state atoms, predict the type of orbital (1s, 2p, 3d, 4f, etc.) from which an electron will be removed to form the +1 ion: (a) Ge; (b) Mn; (c) Ba; (d) Au.

The answers are: (a) 4p; (b) 4s; (c) 6s; (d) 6s

What method should I use to get the correct answers?

Write the electron configuration of each and typically the last orbital will not be completely filled, so that will be the orbital the electron will be removed from.

Be sure that when removing electrons, the electrons from the ns state are removed first before removing those from the (n-1)d state. (e.g. 4s state electrons before 3d electrons)

what this means is, for example in B, 3d^5 comes before 4s^2 when written out, so since 4s^2 is in front that is the orbital you would be using
