Chapter 8: Problem 37

(a) What is meant by the term electronegativity? (b) On the Pauling scale what is the range of electronegativity values for the elements? (c) Which element has the greatest electronegativity? (d) Which element has the smallest electronegativity?

Short Answer

Expert verified
(a) Electronegativity is the ability of an atom to attract the shared electron pair within a covalent bond to itself. (b) The Pauling Scale ranges from approximately 0.7 to 4.0. (c) Fluorine (F) has the greatest electronegativity, with a value of 3.98. (d) Francium (Fr) has the smallest electronegativity, with a value of approximately 0.7.

Step by step solution

01

(a) Electronegativity Definition

Electronegativity is the ability of an atom to attract the shared electron pair within a covalent bond to itself. It is a measure of the relative attraction an atom has for the electrons in a bond, and different elements have different electronegativity values.
02

(b) Pauling Scale Electronegativity Range

The Pauling Scale is an empirical scale that ranks elements based on their electronegativity values. On the Pauling Scale, electronegativity values for the elements range from approximately 0.7 to 4.0.
03

(c) Element with Greatest Electronegativity

The element with the greatest electronegativity is Fluorine (F), with an electronegativity value of 3.98 on the Pauling scale.
04

(d) Element with Smallest Electronegativity

The element with the smallest electronegativity is Francium (Fr), with an electronegativity value of approximately 0.7 on the Pauling scale.
