2.1 - Types of Chemical Bonds(AP)

What is electronegativity?

• Measure of an atom's ability to attract shared electrons

• Measure of an atom's mass

• Measure of an atom's volume

• Measure of an atom's temperature

What is the electronegativity difference for a polar covalent bond?

• Less than 0.5

• Between 0.5 and 1.7

• Greater than 1.7

• Exactly 0.0

What is the result of unequal sharing of electrons in a bond?

• Nonpolar covalent bond

• Polar covalent bond

• Ionic bond

• Metallic bond

What type of bond is formed when there is a transfer of electrons between atoms?

• Ionic bond

• Covalent bond

• Metallic bond

• Hydrogen bond

What type of bond is classified differently and is formed between only metals?

• Metallic bond

• Ionic bond

• Polar covalent bond

• Nonpolar covalent bond

Which type of elements tend to have the highest electronegativity?

• Nonmetals

• Metals

• Noble gases

• Alkali metals

What type of structure do ionic compounds form?

• Electron-sea structure

• Covalent bond

• Lattice of alternating plus-minus

• Random arrangement

In the NaCl lattice, what makes Na+ more stable?

• Being surrounded by other Na+

• Being surrounded by oppositely charged Cl-

• Being isolated

• Being surrounded by water molecules

What is electricity defined as in the context of metals?

• Movement of protons

• Movement of neutrons

• Movement of electrons

• Movement of atoms

Why are core electrons more difficult to remove?

• They are closer to the nucleus

• They are further from the nucleus

• They are involved in bonding

• They are in the outer shell
