Chapter 13, Problem 19E

Interpretation Introduction

Interpretation:

Whether there are differences among the answers in exercises 17 and 18 or not should be predicted by using the values of electronegativity’s of elements.

Concept Introduction:

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.

The term which determines the ability of an atom to attract the bonding electron pairs towards itself is known as electronegativity.
