Module 7 Covalent Bonding Review

Front

What are polar covalent and nonpolar covalent compounds?

Back

Polar covalent compounds have unequal sharing of electrons, resulting in a dipole moment, while nonpolar covalent compounds have equal sharing of electrons.

Front

Do polar covalent and nonpolar covalent compounds exist as individual molecules?

Back

True

Front

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What type of bond is present in a nitrogen molecule (N2)?

Back

A nitrogen molecule (N2) has a triple bond.

Front

How many electrons do the nitrogen atoms share in a nitrogen molecule (N2)?

Back

The nitrogen atoms share 6 electrons.

Front

What is a Lewis dot structure?

Back

A Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

Which Lewis dot structure represents the molecule fluorine (F2)?

Back

The correct Lewis dot structure for fluorine (F2) is structure B.

Front

What type of compounds dissolve in water?

Back

Polar covalent compounds dissolve in water.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.
