what is a metallic bond?
the electrostatic attraction between the positive metal ions and negative delocalised electrons
how are metallic bonds formed and how are they arranged?
when metal atoms lose an electron to form positive ions surrounded by negative delocalised electrons
arranged into a regular (giant) lattice structure
what does the strength of a metallic bond depend on?
number of protons
more protons = stronger bond
number of free electrons
more electrons = stronger bond
size of ion
smaller ions = stronger bond
what are the properties of metals?
good conductors of heat and electricity
free delocalised electrons which can carry thermal energy/a charge
high melting and boiling points
due to strong electrostatic forces of attraction
malleable and ductile as layers of ions can slide over each other
