How are metals classified in the periodic table?
Most metals occur towards the left and downwards on the periodic table. In fact, most of the elements on the periodic table are considered metals; 91 of the 118 known elements are classified as metals. Non-metals constitute the majority of remaining elements.
How is the periodic table divided into metals and nonmetals?
In the periodic table metals are placed on the left hand side and centre whereas non-metals are placed on right side of periodic Table. The metals and non-metals are separated by the elements which show the properties of both metals and non-metals and are called metalloids.
