Description

Metal:
On heating gypsum at 373 K, it loses water molecules and becomes calcium sulphate hemihydrate (CaSO4. ½ H2O). This is called Plaster of Paris, the substance that doctors use as plaster for supporting fractured bones in the right position. Plaster of Paris is a white powder and on mixing with water, it changes to gypsum once again, giving a hard solid mass.

Examples of metals include copper, silver, iron, mercury, lead, aluminium, gold, platinum, zinc, nickel, and tin.

Physical Properties of Metals:

  1. Lustre: Metals exhibit a characteristic metallic lustre, which refers to their shiny appearance when polished or freshly cut. This lustre arises due to the reflection of light by the free electrons on the metal surface.
  2. Malleability: Metals can be hammered or rolled into thin sheets without breaking. This property is called malleability and is due to the ability of metal atoms to slide past each other when subjected to pressure.
  3. Ductility: Metals can be drawn into thin wires without fracturing. This property, known as ductility, results from the orderly arrangement of metal atoms, allowing them to be drawn into long, thin wires.
  4. Conductivity: Metals are good conductors of heat and electricity. This property arises from the presence of free electrons that can move through the metal lattice, allowing the transfer of heat or electricity.
  5. Density: Metals generally have high densities. Common metals like iron, copper, and lead are denser compared to non-metals owing to their closely packed atomic structures.
  6. Melting and Boiling Points: Metals typically have high melting and boiling points. This characteristic is due to the strong metallic bonds between metal atoms, requiring significant energy to break these bonds.
  7. Sonorous: Metals produce a characteristic ringing sound when struck, known as Sonorousness. This property is due to the vibrations of metal particles when hit, creating a clear sound.
  8. Thermal Expansion: Metals expand when heated and contract when cooled. This property of thermal expansion is useful in various applications, from designing structures to manufacturing.

The physical properties of metals make them crucial materials in various industries. Their malleability, conductivity, and other properties make metals essential for construction, manufacturing, electrical wiring, and technological advancements.
