Ionic, Covalent and Metallic Bonding

Front

What type of bond is formed when electrons are shared between atoms?

Back

Covalent bond.

Front

What type of bond is characterized by the transfer of electrons from one atom to another?

Back

Ionic bond.

Front

What type of bond involves a sea of delocalized electrons that are free to move?

Back

Metallic bond.

Front

What are the typical properties of ionic compounds?

Back

High melting and boiling points, conduct electricity when dissolved in water.

Front

What are the typical properties of covalent compounds?

Back

Low melting and boiling points, do not conduct electricity.

Front

What is the main reason metallic substances conduct electricity?

Back

The mobility of valence electrons.

Front

What type of bond is present in water (H2O)?

Back

Covalent bonds.

Front

What is the difference between a polar covalent bond and a nonpolar covalent bond?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is an example of a substance that exhibits metallic bonding?

Back

Copper (Cu).

Front

What is the octet rule in relation to bonding?

Back

Atoms tend to bond in a way that gives them eight valence electrons.
