Study Notes

Properties of Metals

  • Malleability allows metals to be hammered into thin sheets without breaking.
  • Ductility is the property enabling metals to be drawn into thin wires.
  • Metals can produce a deep or ringing sound when struck due to their sonorous property.

Conductivity and Reactivity

  • Silver is known for being the best conductor of heat among metals.
  • Metals are generally good conductors of electricity due to their high density of free electrons.
  • Sodium is stored under kerosene oil to prevent its high reactivity with oxygen.

Melting Points

  • Tungsten has the highest melting point among the listed metals.
  • Mercury has the lowest melting point, remaining liquid at room temperature.

Chemical Compounds

  • The chemical formula for sodium hydroxide is NaOH.

Metal Behavior

  • Aluminum shows amphoteric oxide behavior, acting as both an acid and a base in reactions.
  • Tin is noted as the exception to the general strength of metals, being relatively weak.
  • Gold is the most ductile metal, capable of being stretched into very thin wires.

Conductivity

  • Copper is commonly recognized as a highly conductive metal for electricity.
  • Lead is the poorest conductor of heat among the mentioned metals.

Exceptions in State

  • Initials such as mercury and gallium represent exceptions, as they are liquids at room temperature.

Matching of Metals and Properties

  • Various metals exhibit unique properties that match specific applications, such as:
    • Metals can be associated with distinct actions or uses like their conductivity or reactivity with oxygen.
    • Each metal has a characteristic sound property associated with its physical structure and composition.

Application in Daily Life

  • Metals like aluminum are commonly used in foil form for packaging, cooking, and insulation purposes.
  • Transition metals like iron are widely utilized in construction and manufacturing due to their strength.

These notes summarize the essential properties, behaviors, and applications of various metals, emphasizing both general characteristics and exceptions within the metal category.
