Explanation / Answer

number of electrons = 36 + 2+ 10+ 5 = 53

Z = 53, then this is Iodine

2.

it is from the family of halogens

3.

this is a nonmetal, it has a very low metallic properties, besides, it is a hallogen

4.

for the last electorn 5p5

then

s,p,d = 0,1,2

n = 5; l = 2; ml = 2, ms = +1/2
