Describe the bonding in metals using calcium as an example. You should use the words IONS and DELOCALISED?

Thanks :)

2+ calcium ions are arranged in layers. These layers can easily move over each other, making metals both malleable and ductile. The calcium ions are surrounded by a sea of free moving delocalised electrons. These electrons come from the outer shell of the calcium atoms, which is why they become ions. Thes structure will contain 2 electrons for every 1 calcium ion, because calcium has 2 electrons in their outer shells. The negative electrons and the positive ions will form very strong electrostatic forces of attraction, which hold the structure together.
