Periodic Table Classification

Elements are classified into metals, non-metals, and metalloids based on their properties and positions in the periodic table. Metals, typically found on the left side, are good conductors of heat and electricity, while non-metals, located on the right, are poor conductors. Metalloids, which have properties of both metals and non-metals, are found along the zig-zag line that separates these two categories.

Properties of Metals

Metals are characterized by their malleability, ductility, and high electrical and thermal conductivity. They tend to lose electrons during chemical reactions, forming positive ions. Common examples include potassium (K) and barium (Ba), which are both highly reactive and exhibit metallic luster.

Properties of Non-Metals

Non-metals are generally poor conductors of heat and electricity and are not malleable or ductile. They can gain or share electrons in chemical reactions, forming negative ions or covalent bonds. Elements like iodine (I) and oxygen (O) are typical non-metals, exhibiting diverse physical and chemical properties.
