The atoms in a metallic element are...

All the same size

What do metallic elements form?

They form giant ionic structures in which layers of atoms are arranged in a regular pattern

When metals are bonded to form giant structures, what happens to the outer shell of electrons?

They become delocalised and can move freely between the positively. This produces a lattice of positively charged ions in a sea of moving electrons

What holds together the giant structure?

The delocalised electrons strongly attract the positive ions
