20.

Metals are shapeable (malleable and ductile) because

a)

The relatively empty outer shell of the metal atoms allows electrons to flow through the metal.

b)

metals atoms are bonding to the sea of electrons and when the metal atoms are moved the sea of electrons move with it. No chemical bonds are broken and no repulsion forces are produced.

c)

metals atoms have many electron energy levels with relatively small energy differences allowing electrons to absorb photons, become excited, then return to their ground state giving off photons of light

d)

metal atoms are tightly packed but because they are bonded to the sea of electrons and not each other, they are free to vibrate thus colliding with neighboring atoms causing them to vibrate more. Additionally the delocalized sea of electrons are free to move around.

21.
