Question
Chapter 12, Problem 9CE
Interpretation Introduction
Interpretation:
General trends for the increasing electronegativity in the periodic table are to be stated.
Concept introduction:
Electronegativity is the measure of the attracting power for electrons by the element. Each element has the ability to attract the electrons because of the positive nuclear charge. Atoms having highest attraction power for the electrons are highly electronegative.
