Metallic Bonding
Transition Metals
o Transition metals are different because their properties are very similar across a period as well as in columns.
§ b/c as you go across the period you are adding inner electrons rather than valence electrons. These inner e don’t as readily participate in bonding. So many of the metals have, effectively, the same number of valence electrons and therefore the same chemical properties.
o Common characteristics
§ Multiple oxidation states
· Results in different colors
· Results in usefulness as catalysts
§ Complex ions
· Results in usefulness as catalysts
§ Colored
§ Paramagnetic
