​

Properties or characteristics of Metals

Location on the Periodic Table

• The dark zig-zag line on the Periodic Table separates the metals from the nonmetals.

• Most of the elements on the Periodic Table are metals and are found to the left of the zig-zag line.

• Group 1 Metals are called ALKALI METALS.
