Between which two elements is the difference in metallic character the greatest?

Arrange these elements in order of decreasing metallic character: Sr, N, Si, P, Ga, Al.

Consider the elements: Na, Mg, Al, Si, P. c. Which element is least metallic?

Neither strontium (Sr) nor antimony (Sb) is shown in the activity series of Table 4.5. Based on their positions in the periodic table, which would you expect to be the better reducing agent? Will the following reaction occur? Explain.
