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 |
