Quiz on Ionic Bonding

Which of the following compounds is most likely to have ionic bonding?

• CO₂

• HCl

• NaCl

• CH₄

When a sodium atom forms an ion, it:

• Gains one electron

• Loses one electron

• Gains two electrons

• Loses two electrons

Which pair of ions would form the strongest ionic bond?

• Na⁺ and Cl⁻

• Mg²⁺ and O²⁻

• K⁺ and Br⁻

• Ca²⁺ and F⁻

Ionic bonding occurs between:

• Two non-metals

• Two metals

• A metal and a non-metal

• A metalloid and a non-metal

Which of the following has a structure consisting of a giant ionic lattice?

• H₂O

• SiO₂

• NaCl

• I₂

The high melting point of MgO compared to NaCl is due to:

• Greater molecular mass

• Covalent character in the bond

• Stronger electrostatic forces due to higher charge

• More electrons in the outer shell

Which of the following statements about ionic compounds is correct?

• They conduct electricity when solid

• They are usually gases at room temperature

The ionic radius of Na⁺ is smaller than that of Na because:

• It has gained a shell of electrons

• The number of protons has increased

• It has lost a shell of electrons

• It has more electron shielding
