Understanding Chemical Bonding

What is the primary reason a piece of paper tears more easily than a steel bar?

• Paper and steel have the same particle strength.

• Steel particles are weaker than paper particles.

• The force applied is greater than the strength of paper particles.

• Paper has stronger atomic bonds than steel.

Which type of bonding involves the transfer of electrons from a metal to a non-metal?

• Covalent bonding

• Metallic bonding

• Ionic bonding

• Hydrogen bonding

What is a characteristic property of ionic compounds?

• Exist as gases

• Poor electrical conductivity

• High boiling points

• Low melting points

In covalent bonding, what do non-metal atoms do to achieve stability?

• Gain electrons

• Lose electrons

• Share electrons

• Transfer electrons

Why are metals good conductors of electricity?

• They have a sea of free electrons.

• They do not conduct electricity.

• They have tightly bound electrons.

• They have high melting points.
