Why Do Transition Metals Show a Lot of Chemical Similarities

Multiple Choice

Why do transition metals show a lot of chemical similarities within a given period?

A) The valence s and p electrons affect their chemistry more so than the inner d and f electrons,which do not participate in bonding as easily.
B) The number of electrons within a given period varies only slightly and is sometimes identical because these metals have more than one ionic form.
C) All elements in a given period,including the representative elements,have a lot of chemical similarities due to the gradual increase in atomic number.
D) The transition metals always fill their s and p orbitals first before filling their d orbitals,which affects their chemistry.
E) None of the above is correct.
