(a)
Interpretation:
The elements that have electronegativity values more than that of carbon has to be given using the information from Figure 5-11.
Concept Introduction:
Close relationship between ionic and covalent bonding models becomes apparent if the bond polarity and electronegativity is considered. Electronegativity is the measure of relative attractive for the shared pair of electrons in a bond. Higher the electronegative value for an atom, the more it attracts the shared pair of electrons towards itself.
In Periodic table, when moving from left to right in a period, the electronegativity value increases. While moving from top to bottom within group, the electronegativity value decreases. Nonmetals have higher electronegativity values than metals. Metals gives electrons and nonmetals accepts electrons.
(b)
Interpretation:
The elements that have electronegativity values less than 1.0 has to be given using the information from Figure 5-11.

- What is the general trend in electronegativity across a period on the periodic table? Electronegativity decreases left to right across a period. Electronegativity increases from left to right across a period. What is the general trend in electronegativity down a group on the periodic table? Electronegativity decreases as you move down a group on the periodic table. Electronegativity increases as you move down a group on the periodic table. How does the trend in electronegativity relate to the general trends in ionization energy and the magnitude of electron affinity? The general trends in both ionization energy and the magnitude of electron affinity are opposite of the trend in electronegativity. The general trend in ionization energy is the same as the trend in electronegativity and the general trend in the magnitude of electron affinity is opposite of the trend in electronegativity.
