1c. The strong forces also gives a making the average heavier than an average .
1d. The presence of in the structure keeps the bonding intact when metals are bent or hammered giving them .
1e. Also, these gives metals as regards heat and electricity.

2a. When electrons are transferred from (usually) a atom (e.g. sodium) to a atom (e.g. chlorine) an is formed.
2b. Sodium loses an electron to form a singly charged and chlorine gains an electron to form a singly charged .
2c. In an ionic compound, the is the between the neighbouring positive ions and negative ions.
2d. The strong forces holding this giant ionic lattice together give these ionic compounds a and .

3a. When ionic compounds are melted they are found to in a process called . using electrical contacts called .
3b. In this process, s move to the negative electrode (cathode) and s are released.
3c. At the same time, s move to the positive electrode (anode) and s are formed.
