The elements sodium and chlorine react together to form the compound sodium chloride, which has a giant ionic lattice structure. 

a. What type of structure do the elements

(i) Sodium 

(ii) Chlorine have?

b. Draw a diagram to represent how the ions are arranged in the crystal lattice of sodium chloride.

c. Explain how the ions are held together in this crystal lattice.

d. Draw diagrams to show how the electrons are arranged in a sodium ion and a chloride ion.

(The proton numbers of sodium and chlorine are 11 and 17, respectively.)

e. Make a table showing the properties of the three substances sodium, chlorine and sodium chloride. Include in your table:

(i) The physical state at room temperature

(ii) Solubility in (or reaction with) water

(iii) Colour

(iv) Electrical conductivity.
