Worked practice questions

What holds oppositely charged ions together?

  1. Van der Waals attraction
  2. Covalent electron sharing
  3. Dipole-induced attraction
  4. Electrostatic attraction
Show answer and solution

Correct answer: D. Electrostatic attraction

Oppositely charged ions attract electrostatically in an ionic bond.

Which atom becomes a cation when it loses electrons?

  1. The electron-losing atom
  2. The neutral molecule
  3. The shared electron pair
  4. The electron-gaining atom
Show answer and solution

Correct answer: A. The electron-losing atom

Losing electrons gives an atom a positive charge.

What charge does an atom gain by accepting electrons?

  1. Alternating charge
  2. No electric charge
  3. Positive charge
  4. Negative charge
Show answer and solution

Correct answer: D. Negative charge

Gaining electrons gives an atom a negative charge.
