property of metals

Cards (17)

  • what are the properties of metals
    strong
    hard
    malleable (can be shaped)
    ductile (can be made into wires)
    good conductors of heat and electricity
    high melting point
  • metal atoms form a giant lattice with a regular arrangement
  • lattice structure:
  • any crystal structure must have a lattice structure
  • what does the blue and red symbolize
    delocalized electrons (blue) and metal ions (red)
  • what is a delocalised electron
    free to move across several atoms in a metal
  • what are the lattice of positive metal ions surrounded by
    what you call a sea of delocalised electrons
  • what is metallic bonding
    electrostatic attraction between metal ion lattice and sea of delocated electrons
  • what holds metal together
    the electrostatic attraction
  • electrons on each metal are free to move through the structure to form a sea of electrons
  • what does covalent electrons mean
    localised electron attractions
  • what charge are metal atoms left with having released electrons into the sea
    positive
  • lattice structure can break from too many layers
  • what is an alloy
    is a mixture of two or more elements, where at least
    one element is a metal
  • how are metals such good conductors of electricity
    they contain delocalised electrons that are charged and can freely move, allowing the flow of electricity
  • why do metals have a high melting point
    because of its strong electrostatic attraction between ions and delocalised electrons - requires a lot of energy to break
  • how can metals bend easily
    metals bend easily because they have a lattice structure which is arranged in layers - these layers move over each other, allowing metals to be reshaped
