What type of bonding is formed when the electronegativity difference between two atoms is very small?

• Metallic bonding

• Polar covalent bonding

• Ionic bonding

• Nonpolar covalent bonding

In a nonpolar covalent bond, how are the shared electrons distributed between the atoms?

• equally

• unequally

• only on one atom

• alternating between the atoms

What is the general range of electronegativity difference for a polar covalent bond?

• 4-5

• 0.5-1.7

• 0.1-0.5

• 2-3

In an ionic bond, what happens to the electrons?

• Electrons are gained by both atoms.

• Electrons are shared between atoms.

• Electrons are transferred from one atom to another.

• Electrons are lost by both atoms.
