Metals are elements that are usually hard, lustrous, malleable, ductile, and good conductors of heat and electricity.

Malleability is the property of metals that allows them to be beaten into thin sheets without breaking. Examples include aluminum foil and gold leaf.

Sonorous materials produce a ringing sound when struck. Most metals, like iron and copper, exhibit this property.

Conduction of heat is the transfer of heat from one point to another within a material. Metals are good conductors, while wood is a poor conductor.

Good conductors of electricity include metals like copper, aluminum, and iron, which allow electric current to flow easily.

Rusting is the process of formation of brown deposits (rust) on iron due to its reaction with moisture and air.

Rusting can be prevented by painting, oiling, greasing, or galvanizing (applying a protective zinc layer) iron.

Non-metals are elements that typically lack the properties of metals, such as being dull, brittle, and poor conductors of heat and electricity.

Oxygen, a non-metal, is essential for respiration and survival in living organisms.

When magnesium burns in air, it produces a dazzling white flame and forms magnesium oxide, a white powder.

Iron develops rust when exposed to moist air, which is a form of corrosion.

Non-metal oxides are typically acidic in nature, such as sulfur dioxide forming sulfurous acid when dissolved in water.

Metals are malleable (can be shaped into sheets), while non-metals are not malleable and more likely to break.

Metals are used in utensils, tools, electronics, and construction due to their strength and conductivity.

Metals have a shiny appearance due to their ability to reflect light, a property known as metallic lustre.

Mercury is a metal that is found in liquid state at room temperature, often used in thermometers.

Burning sulfur produces sulfur dioxide gas, which is acidic when dissolved in water.

Rusting weakens iron structures, leading to damage that requires costly repairs and replacements.
