Use this information for the following five questions. This table lists the melting temperatures of the metallic elements of Group 1A.

Element in Group 1A	Melting Temperature
Lithium	180.54C
Sodium	97.72C
Potassium	63.38C
Rubidium	39.31C
Cesium	28.44C

Q: What trend in melting temperature do you observe as you go down the column? Which of the two properties (atomic volumes or ionization energies) shows the same trend as the melting points? Q: What would you predict about the forces that hold atoms of cesium together in the solid metal compared to the forces that hold atoms of lithium together in the solid metal? Explain your reasoning when making your prediction.
