Properties of Metals and Non-Metals

Metals make up the vast majority of the elements on the periodic table, occupying the left side and center.

Uranium is a heavy, radioactive metal found in the actinide series of the periodic table, commonly used as fuel in nuclear reactors.

Copper is highly conductive, malleable, and corrosion-resistant, making it ideal for electrical wiring, plumbing, and cookware.

Chlorine is a powerful disinfectant and oxidizing agent used to treat drinking water, maintain swimming pools, and as a component in bleach.

Iron is a fundamental structural metal used to create steel, which is essential for buildings, machinery, and infrastructure.

Aluminum is lightweight, strong, and corrosion-resistant, making it suitable for aerospace, construction, and kitchenware.

Gold, silver, copper, and platinum are all classic examples of metals, known for their luster, conductivity, and malleability.

Oxygen, carbon, chlorine, and hydrogen are all non-metals, which typically lack metallic luster and are poor conductors of heat and electricity.

Non-metal oxides (acidic oxides) react with water to form acidic solutions, such as carbon dioxide forming carbonic acid.

Non-metals do not possess magnetic properties; magnetism is a characteristic associated with certain metals like iron, nickel, and cobalt.

Sonorousness, the ability to make a ringing sound when struck, is a property of metals, not non-metals.

Most non-metals are poor conductors of electricity (insulators). Graphite is a notable exception, but it does not change the general rule for non-metals.

Non-metals are generally poor conductors of heat, which is why they are often used as thermal insulators.

Ductility is the ability of a material to be stretched into a wire, which is a defining physical property of metals.

Brittleness is the tendency of a material to fracture or break under stress, which is characteristic of non-metals in their solid state.

Metals are typically strong and have high tensile strength, which is why they are widely used in construction and engineering.

Non-metals generally have lower densities compared to metals, which are typically dense and heavy for their size.

Most metals are solids at room temperature. Mercury is the notable exception as it is a liquid.

Metals possess a characteristic metallic luster, which makes them appear shiny when polished or freshly cut.
