1.	Define the terms metals, non-metals and metalloids.Give one example in each case
Answer» Metals : A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile. A metal may be a chemical element such as iron, or an alloy such as stainless steel. Example : Iron Non-metal : Non-metals are those which lack all the metallic attributes. They are good insulators of heat and electricity. They are mostly gases and sometimes liquid. Some they are even solid at room temperature like, Carbon, sulfur and phosphorus.
