Predicting Bond Type

What is the result when the difference in electronegativity between two atoms is more than about 2?

• No bond is formed

• A nonpolar covalent bond is formed

• A polar covalent bond is formed

• An ionic bond is formed

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

• Ionic bond

• Metallic bond

• Polar covalent bond

• Nonpolar covalent bond

What happens in a polar covalent bond?

• Electrons are shared evenly

• Electrons are taken, not shared

• One atom holds the electrons more tightly

• No electrons are shared

What is the charge of an atom that steals an electron?

• Partially positive

• Neutral

• Negatively charged

• Positively charged

What symbol denotes a partially negative atom in a polar covalent bond?

• Delta plus

• Delta minus

• Sigma plus

• Sigma minus

What type of bond involves the electrostatic attraction between ions of opposite charge?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

If the electronegativity difference between two atoms is less than 0.5, what type of bond is formed?

• Ionic bond

• Polar covalent bond

• Metallic bond

• Nonpolar covalent bond

How can you predict the type of bond that will form between two elements?

• By comparing their densities

• By comparing their electronegativities

• By comparing their masses

• By comparing their atomic numbers
