metalatoms 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
electrostaticattraction 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
