Formulas Poker - Experiment 26

Students can practice writing chemical formulas in a game.

Each deck should contain:

  1. At least one card with each of the following ions(47cards):
    Ba +2
    Na +1
    Ca +2
    Li +1
    Pb +2
    Zn +2
    Be +2
    Mg +2
    Ag +1
    K +1
    V +3
    Ni +3
    Cu +2
    Cu +3
    Fe +2
    H +1
    Fe +3
    Sc +3
    Al +3
    Hg +2
    Sn +1
    Rb +1
    NO3 -1
    NO2 -1
    SO4 -2
    SO3 -2
    HSO4 -1
    CO3 -2
    HCO3 -1
    PO4 -3
    HPO4 -2
    NH4 +1
    OH -1
    ClO4 -1
    CrO4 -1
    Cl -1
    AsO4 -2
    C2H3O2 -1
    H2PO4 -1
    I -1
    S -2
    O -2
    F -1
    N -3
    Br -1
    P -3
  • One blank or FREE card
  • Fifteen cards: five with each of the following subscripts: 1 2 3
  • Procedure

    1. This game is played as a 5-card draw. The dealer will pass out 5 cards to each player from the shuffled deck, placing all remaining cards in a central stack.
    2. Each player may discard as many as 3 cards in one rotation—taking as many cards from the central stack as s/he discards. Play begins with the player to the right of the dealer. Players try to make a chemical formula that uses as many of their cards as possible. If they cannot play, they must pass. It is possible to make two chemical formulas in one play. Once a player uses a number of cards to make a formula, that player should draw, from the central stack, as many cards as s/he used. Play then passes to the player on the right.
    3. Total the score by the number of cards that a player is able to use to make a chemical formula. It is possible for a player to score as many as 5 points per hand. See Sample Score sheet. Each player has her/his own score sheet.
    4. Play continues until no more formulas can be made.
