Transition Elements from the Right Side of the Periodic Table

Transition elements from the right side of the periodic table are generally found as

A) sulfides because they tend to give up bonding electrons and form crystals with high lattice energies with sulfur.
B) sulfides because their electronegativities favor formation of covalent bonds with the polarizable sulfide anion.
C) oxides because they tend to give up bonding electrons and form crystals with high lattice energies with oxygen.
D) oxides because oxygen, with its high electronegativity, forms strong covalent bonds with them.
E) None of these choices is correct.
