Exploring Covalent Bonds and Their Properties

What is a covalent bond?

• A bond where atoms are held together by gravitational forces.

• A bond where atoms are held together by magnetic forces.

• A bond where electron pairs are shared between atoms.

• A bond where electrons are transferred between atoms.

Why do covalent bonds not conduct electricity?

• Because the atoms are too close together.

• Because the atoms are too far apart.

• Because the electrons are locked in position.

• Because the electrons are free to move.

What is the Van Arkel-Kepler triangle used for?

• To determine the boiling point of compounds.

• To classify bonds as ionic, covalent, or metallic.

• To measure the strength of metallic bonds.

• To calculate the molecular weight of compounds.

Which compound is more ionic according to the Van Arkel-Kepler triangle?

• Lithium chloride

• Methane

• Water

• Sodium chloride

What does the special arrow with a little cross at the end denote?

• The direction of electron flow

• The location of the negative area

• The location of the positive charge

• The strength of the bond

What must a molecule have to be considered polar?

• Neither polar bonds nor asymmetry

• Both polar bonds and asymmetry

• Only asymmetry

• Only polar bonds

Which type of bond is the strongest?

• Double bond

• Triple bond

• Metallic bond

• Single bond

Why are triple bonds the shortest?

• Because they involve the least atoms

• Because they have the most electron repulsion

• Because they involve the most atoms

• Because they have the least electron repulsion

What increases the strength of ionic bonds?

• The distance between the ions

• The size of the positive ion

• The degree of positiveness and negativeness of the ions

• The number of shared electrons

What factor increases the strength of metallic bonds?

• A large positive ion

• A small positive ion

• A large negative ion

• A small negative ion
