Chemical Bonding Practice Tests

These Grade 10 Science practice tests develop ionic, covalent, and metallic bonding, valence electrons, the octet rule, Lewis structures, compound formulas, polarity, molecular shape, and intermolecular forces.

Skills covered

  • Distinguishing ionic, covalent, and metallic bonds by tracking electron transfer, sharing, and mobility
  • Using valence electrons, the octet rule, Lewis structures, lone pairs, and bond order
  • Writing neutral ionic formulas for common cations and anions using charge balance
  • Explaining electronegativity, polar and nonpolar bonds, molecular polarity, and molecular shape
  • Comparing hydrogen bonding, dipole-dipole forces, London dispersion forces, and intramolecular bonds

How to use these practice tests

Count valence electrons first, then decide whether atoms transfer or share electrons. For formulas, balance charges; for molecular polarity, consider both bond polarity and the overall shape.
