Chapter 23 .1, .4, .5, .6, .7, .8 General Properties - Know electronic config+exceptions - Similar metallic radius - Know oxidation states ; they have multiple oxidation states, giving them their special properties - Manganese has an oxidation state of +7 Atomic Radii- Color/Magnetism - Little difference between 4/5/6 th periods due to the Lanthanide contraction ( 4f shell ) due to the screening effect - Higher stability for higher oxidation states (lower element in the periodic table) - Can exhibit both ionic/covalent characters; play a role in catalysis - Form colors in solutions (every oxidation state has a different color) same principle as changes in energy level ex. Half filled d shell to full d shell

Unformatted text preview: -* Electronic transitions in the partially filled d shell gives color to the solutions-Ferromagnetism: can be made into a magnet 23-4 23-8-Scandium 3+ = Argon= doesnt do shit; very rare element-Titanium: -Vanadium: can have every possible oxidation state aka the whore-Copper/silver/gold Group uses d electrons in chemical bonding, has only 1 s electron -Lanthanides: chemical behave the same as La (z=57), most common oxidation state is Ln3+=Xe config-* not reactive-Reactivity increases as you do down a group...
