Electronegativity Difference

Electronegativity is a measurement of the ability of a nucleus to...

• attract bonding electrons

• attract other nuclei

• attract elenece in the non-valence energy levels

A bond with a partially negative end and a partially positive end is:

• ionic

• polar

• non-polar

• isometric

The polarity of a bond is determined by...

• The sum of the electronegativities of the two atoms

• The difference in the electronegativities of the two atoms

• The ionization energy required by the two atoms

The electrons in a POLAR covalent molecule are shared...

• Evenly

• Unevenly

• Electrons are not shared

In a polar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally

In a nonpolar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally

Partial charges are present in which type of bond(s)?

• Ionic

• Nonpolar Covalent

• Polar Covalent

• Both Polar Covalent and Ionic

• All covalent

In a polar covalent bond, which atom will have a partial negative charge? (Select the TWO that apply)

• The atom that attracts fewer electrons

• The atom with the greater electronegitivity

• The atom that attracts more electrons

• The atom with the lower electronegativity

In this Lewis structure (Displayed formula), the symbol above F is a partial negative sign which means...

• electrons are being transferred to Fluorine

• electrons are less attracted to F than H

• electrons are more attracted to F than H

• Fluorine has formed a cation
