Q:

Do metal properties have high or low melting points?

A:

Metals have high melting and boiling points compared to non-metals because they are good conductors of heat and electricity, while non-metals are poor conductors of heat and electricity. Metals are solids at room temperature except mercury which is the only metal that is a liquid.

Metals are strong, while non-metals are brittle. Metals produce sound when they are struck, while non-metals do not. Metals are lustrous and shine, while non-metals are dull. Metals have high density compared to non-metals.

Metals such as aluminum, gold and silver are malleable and can be beaten into sheets. Metals such as aluminum and copper are ductile, and they can be pulled into wires. Metals form basic oxides such as magnesium oxide while non-metals form acidic oxides such as sulphur dioxide, sulphur trioxide and carbon dioxide.

    What happens in a condensation reaction?

    A:

    In a condensation reaction, two reactants react to form water or ammonia and one other byproduct. As long as either water or ammonia is formed and is the only byproduct, a reaction is considered a condensation reaction. A condensation reaction is not to be confused with the process called condensation, where water vapor turns to liquid after losing heat.

  • Q:

    Why do solids have definite shapes and volumes?

    A:

    Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overcome these intermolecular forces, so the solid remains in the same state.
