POST TRANSITION METALS
Post Transition Metals
By: Cade Murray and Lauren Eusanio
Physical and Chemical Properties
Elements
Oxidation Numbers
13,31,49-50,81-83,113-116
Post Transition Metals
Most of the post transition metals have multiple possible oxidation states. Since elements 113-116 are man-made, they do not have a known oxidation state.
Post-transition metals are the metallic elements in the periodic table located between the transition metals and the metalloids
Physical Properties
Chemical Properties
- Brittle/soft
- Malleable
- High density
- Low boiling points
- Covalent bonding tendencies
- Can form half-metallic compounds
- More electronegative than transition metals
Valence Shell Electrons
Aluminum, Gallium, Indium, Thallium and Ununtrium all have 1 valence electron
Tin, Lead and Flerovium have 2 valence electrons
Bismuth and Ununpentium have 3 valence electrons
Livermorium has 4 valence electrons
Interesting Facts and Uses
- They are also called poor metals
- They are softer than transition metals and also have lower boiling points than them
- Bismuth is used in Pepto- Bismol
- Tin is used for plating steel and soldering
