what occurs in metallic bonding?
outer electrons
loosely held
electrons can move freely
creates sea of
delocalised electrons
metal ions
are held together by
electrostatic attraction
creates strong bond between positive and negative metal ions
why are metals good conductors of heat and electricity?
electrons
can carry energy quickly through metal
why are metals malleable?
layers of atoms can slide without breaking
bonds
why do metals have high boiling/melting point?
requires lots of energy to break strong
attraction/bond
what is metallic bonding between?
metal atoms
