Question

arrange the following elements in order of decreasing metallic character. rank values from strongest to weakest metallic character. to rank items as equivalent, overlap them.

Explanation:

Step1: Recall metallic character trends

Metallic character increases down a group and decreases across a period (left to right) on the periodic table.

Step2: Locate elements on periodic table

• Sr (Group 2, Period 5), Ga (Group 13, Period 4), Al (Group 13, Period 3), Si (Group 14, Period 3), P (Group 15, Period 3), N (Group 15, Period 2)

Step3: Rank by metallic character

Down a group, Ga > Al; across a period, Sr > Ga > Al > Si > P > N.

Answer:

Strongest: Sr → Ga → Al → Si → P → Weakest: N
