Ionic bonds

What charge does Lithium acquire after losing an electron?

• +1

• -1

• 0

• +2

What is the difference between ionic and covalent bonds?

• Ionic bonds involve the sharing of electrons, while covalent bonds involve the transfer of electrons.

• Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

• Ionic bonds are stronger than covalent bonds in all cases.

• Covalent bonds can only form between nonmetals.

Which elements typically form ionic bonds?

• Metals and nonmetals

• Nonmetals and nonmetals

• Metals and metals

• Noble gases and metals

Can ionic bonds conduct electricity?

• Yes, always conduct electricity in solid form.

• Yes, when dissolved in water or melted.

• No, they never conduct electricity.

• Only in gaseous form.

What happens to the electrons during the formation of an ionic bond?

• Electrons are shared between the metal and nonmetal atoms.

• Electrons are transferred from the metal atom to the nonmetal atom.

• Electrons are lost by both the metal and nonmetal atoms.

• Electrons remain unchanged during the bond formation.

What is the role of electronegativity in ionic bonding?

• Electronegativity determines the color of the bond.

• Electronegativity affects the size of the atoms involved.

• Electronegativity determines how strongly an atom attracts electrons; a large difference in electronegativity between two atoms leads to ionic bonding.

• Electronegativity has no effect on ionic bonding.

What is lattice energy in ionic compounds?

• The energy required to break an ionic solid into gaseous ions.

• The energy released when ions in a gas phase come together to form an ionic solid.

• The energy needed to dissolve an ionic compound in water.

• The energy associated with the formation of covalent bonds.

Give an example of an ionic compound.

• Table salt (NaCl)

• Sugar (C12H22O11)

• Baking soda (NaHCO3)

• Vinegar (C2H4O2)

What is an ionic bond?

• A type of bond formed by the sharing of electrons between atoms.

• A type of bond formed through the transfer of electrons from one atom to another, resulting in the attraction between positively and negatively charged ions.

• A bond that occurs only in metals and is characterized by high conductivity.

• A weak bond that forms between molecules due to temporary dipoles.
