the number of Number of d Unpaired Electrons paired
electrons, for each element given Question: Which two
elements do not follow the trend in the filling of theirds and
3d orbitals. What is the rational for this? SU When transition
metals form ions, they will lose their ns electrons before their
(n-1)d electrons. For example, Til has the electronic
configuration [Ar]3d", NOT [Ar]45 Question 2: Write out the
condensed electronic configurations of c) Mo b) V- a) Zr
Because the ns and (n-1)d valence orbitals of the transition
elements are very close in energy, many or most of the
