State the position of metals, non-metals and metalloids in modern periodic table.

In the modern periodic table, metals are present in the left hand side of the periodic table. As you move towards the right, there is a transition from metals to semimetals (or metalloids). Metalloids are found in the p-block. The right hand side of the periodic table contains non-metals.

Elements of groups 1 and 2 possess high metallic character. Elements of groups 3-12 exhibit a gradual change in the metallic character. Elements like Boron, Silicon, Arsenic, etc form metalloids. Moving further towards the right, non-metals (Oxygen, Fluorine, Chlorine etc) are found.
