Chapter 5.6, Problem 56PP

(a)

Interpretation Introduction

Interpretation:

The valence electronic configuration for halogens should be written.

Concept Introduction:

An outer shell electron(s) which is related with an atom and that electron(s) can take part in the creation of a chemical bond is known as valence electrons.

Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods. The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents transition elements.

In periodic table, different blocks within the periodic table correspond to the s, p, d and f sublevels. Thus, on the basis of increasing atomic number in the periodic table, electronic configuration of atoms can be written.

Interpretation Introduction

The valence electronic configuration for Group 6A (16) should be written.
