Introductory body chemistry

Valence

Twenty-eight questions on particles, bonding, and water. Mostly judgment calls, with a few straight recalls. The sequence stays fixed. A, B, C, and D are redealt at the start of each attempt, then locked so a letter still means the same thing if you step back.

  1. 01ParticlesCharges, the table, shells, ions, isotopes9
  2. 02BondingValence electrons, covalent and ionic bonds6
  3. 03WaterPolarity, hydrogen bonds, and the properties that follow13

Commit

Pick one, then check it. The note is part of the set.

Order

Questions never shuffle. Only the four choices do.

Retake

Same stems, new letters. Compare the idea, not the position.
