1.1. The melting and boiling points of lithium and some lithium halides are shown below:

Identify the pattern, if any, in the melting and boiling points of the lithium halides. 

1.2. Two students, A and B, are comparing the properties of lithium and lithium chloride.

Student A states that both lithium and lithium chloride will conduct electricity, but Student B states that only lithium will conduct electricity. 

State whether Student A, Student B, or neither student is correct. Explain your answer.

1.3. Students A and B went on to discuss the solubility of lithium and the lithium halides in water.

Student A states that both lithium and all of the lithium halides will be soluble in water, but Student B states that only lithium bromide and lithium iodide will be soluble in water.

State which student, if any, is correct. Explain your answer. 

1.4. Describe the bonding process that forms lithium halides, with respect to electrons.
