Types of Bonds and Electronegativity

In covalent bonds, electrons are ___________________

• shared

• gained

• transferred

• lost

Which molecule contains bonds of Greater polarity?

• OF2

• H2O

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.

• electrons are completely transferred between two metals.

• pairs of electrons are shared between two nonmetal atoms.

• two nonmetal atoms are attracted to each other by opposite charges.

What elements generally make an ionic bond?

• metal and nonmetal

• 2 or more nonmetals

• metal

• none of the above

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 sum of ionization energy required by the two atoms

In a polar covalent bond, which atom will have a partial positive 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

Dipoles like the ones shown here show...

• the direction in which electrons localize

• the speed in which an electron is traveling

• the transfer of electrons

• magnetic poles

Order the types of bonds based on the charge of their molecules. (greatest amount of charge to least)

• Polar Covalent --> Ionic --> Nonpolar Covalent

• Ionic --> Nonpolar Covalent --> Polar Covalent

• Nonpolar Covalent --> Polar Covalent --> Ionic

• Ionic -->Polar Covalent --> Nonpolar Covalent
