The elements in the middle and left side of the Periodic Table are all metals.

The elements in the middle and left side of the periodic table are all metals. The atoms of metal elements typically have only 1, 2 or 3 electrons in their outer shells. This means they can readily lose these electrons to form positive ions. In pure form metals are good conductors of heat and electricity, are malleable, and shiny when polished.
