Covalent, Ionic, and Metallic Bonding Explained

What is a covalent bond?

• A bond formed by the transfer of electrons

• A bond formed by the sharing of electron pairs between atoms

• A bond formed by the sharing of protons

• A bond formed by the attraction between ions

In a purely covalent bond, how are the shared electrons distributed?

• They are owned by one atom

• They are transferred to another atom

• They are shared unequally by the bonded atoms

• They are shared equally by the bonded atoms

What is electronegativity?

• The ability of an atom to donate electrons

• The ability of an atom to repel electrons

• The ability of an atom to attract electrons

• The ability of an atom to share protons

What type of bond is formed when the electronegativity difference is 1.7 or less?

• Covalent bond

• Metallic bond

• Non-polar covalent bond

• Ionic bond

Which of the following is a characteristic of a non-polar covalent bond?

• Unequal sharing of electrons

• Transfer of electrons

• Equal sharing of electrons

• Attraction between ions

What happens in an ionic bond?

• Electrons are transferred from one atom to another

• Electrons are shared unequally

• Protons are shared between atoms

• Electrons are shared equally

Which of the following is true about the shape of an ionic bond?

• It has a definite shape

• It has no definite shape

• It is always linear

• It is always tetrahedral

What is a unique property of metallic bonds?

• They are always polar

• They have a definite shape

• They are non-conductive

• They involve electron sharing over many nuclei

Which of the following is NOT a property of metallic bonds?

• Definite shape

• Optic and luster

• Thermal conductivity

• Strength

What is the similarity between metallic bonds and covalent bonds?

• Both are nonpolar

• Both are polar

• Both involve electron transfer

• Both have a definite shape
