The structure of copper is described as a lattice of positive ions in a 'sea of electrons'.
Which statements are correct?
1 Copper has a high melting point because of the strong electrostatic attraction
between the positive ions and the 'sea of electrons'.
2 Copper is malleable because the layers of atoms in the lattice can slide over each
other.
3 Copper atoms can be oxidised to form copper ions by losing electrons.
