The transition metals

• transition medals are good conductors.

• Transition metals are bad conductors

Post transition metals

• They are very brittle or soft

• They have poor mechanical and strength

• They have low melting points lower than those of the transition metals

The metalloids

• The metalloids display properties of metals and nonmetals

• Non metals tend to be stronger

The Halogens

• Halogens interacts with metals to form various salts

• Halogen has 7 valence electrons

The noble gases

• The noble gas has a complete valance shell

• They have a low boiling pint

What is a valance electron?

• An electron that is found on the most outer shell

• An a electron of an atom
