(a)
Interpretation:
The elements that have electronegativity values more than that of sulfur 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 three least electronegative elements have to be listed using the information from Figure 5-11.

- Answer the following questions List three elements that have 2 electrons in their valence shell. List three elements that have filled valence shells. List three elements that are one electron short of having a filled valence shell. As you work your way across the periodic table from left to right in any given row, what it happening to the electronic structure of the atoms? What property of an element is described by its electronegativity? How does electronegativity typically changes going across the periodic table? Why is that? How does electronegativity typically change going down the periodic table? Why is that? On a scale that goes from nonpolar bond to increasingly polar bond to ionic bond, how would you expect these bonds to be ranked? Why? NaCl, CO, OO, CaO, HCl, SiC If the bonds in a molecule are, in fact, polar, would the molecule as a whole also be polar for each of the following shapes?

- Electronegativity is the ability of an element to pull electrons towards itself in a bond. In a bond, the atom with the greater electronegativity will have a partial charge, and the atom with the lower electronegativity will have a partial charge. Fluorine has the higher/lower electronegativity and Francium has the higher/lower electronegativity. Metals like to gain/lose electrons, while nonmetals like to gain/lose electrons. Thus, metals have a electronegativity, while nonmetals have a electronegativity. a. negative b. positive c. lower d. higher e. lose f. gain g. the same h. none of thesearrow_forwardWhich statement does BEST describe the electronegativity values of the elements shown? Electronegativity tends to be lower in the gases than in the solids. Electronegativity decreases with an increasing atomic number within a period. Electronegativity tends to be higher in the metals than in the nonmetals. Electronegativity decreases with an increasing atomic number within a group.arrow_forwardQUESTION 4 Based on the octet rule, phosphorus most likely forms a ion.
