Can you help me arrange P,Mg,N,Br,K in order of incrasing metallic character. Thank you.

Answer 1

lowest metallic Br
P
N
Mg
highest metallic K

This is because as you move left to right on the periodic table, the metallic character of elements increases, and the metallic character decreases as you move down the periodic table.

Answer 2

If I look at Group 15 and move down the table, I see N, P, As, Sb, Bi. Most metallic is at the bottom. Looking at Group 16, I see O, S, Se, Te, Po. Most metallic is at the bottom. Looking at Group 14, I see C, Si, Ge, Sn, Pb. Most metallic is at the bottom. I think metallic character increases as one moves down the table so P is more metallic than N. I would write
Br
P
N
Mg
K
