Metals & Non-metals
Metal and non-metals are two main categories of elements found in the periodic table. They have distinct physical and chemical properties that differentiate them from each other. Let's delve into the details of metals and non-metals.

Metals
- Metals are elements that have properties like luster, conductivity, malleability, and ductility.
- They tend to lose electrons to form positively charged ions.
- Metals are typically found on the left side of the periodic table.
- Some common examples of metals are iron, copper, gold, and silver.

Non-metals
- Non-metals are elements that lack the properties of metals.
- They are poor conductors of heat and electricity.
- Non-metals tend to gain electrons to form negatively charged ions.
- Non-metals are usually found on the right side of the periodic table.
- Examples of non-metals include oxygen, nitrogen, carbon, and sulfur.

Physical Properties
- Metals are usually solid at room temperature (except mercury).
- Non-metals can exist in various states - solid, liquid, or gas.
- Metals have high melting and boiling points compared to non-metals.

Chemical Properties
- Metals react with acids to produce hydrogen gas.
- Non-metals can react with metals to form ionic compounds.
- Metals tend to form basic oxides, while non-metals form acidic oxides.
In conclusion, understanding the properties of metals and non-metals is crucial in the study of chemistry. These elements play a vital role in various chemical reactions and the functioning of the natural world.
