Question

in the periodic table below, shade the p - block elements.

Explanation:

Step1: Recall p - block definition

The p - block elements are those in groups 13 - 18 of the periodic table. Their outermost electron configuration ends with $ns^{2}np^{1 - 6}$ (except He which has $1s^{2}$).

Step2: Identify elements in groups 13 - 18

Group 13: B, Al, Ga, In, Tl; Group 14: C, Si, Ge, Sn, Pb; Group 15: N, P, As, Sb, Bi; Group 16: O, S, Se, Te, Po; Group 17: F, Cl, Br, I, At; Group 18: Ne, Ar, Kr, Xe, Rn.

Answer:

Shade the elements: B, C, N, O, F, Ne, Al, Si, P, S, Cl, Ar, Ga, Ge, As, Se, Br, Kr, In, Sn, Sb, Te, I, Xe, Tl, Pb, Bi, Po, At, Rn.
