Discovering Atomos Lessons 1 & 2 - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

  20. The central core of an atom. It's made up of protons and neutrons.
    nucleus
  21. Two or more elements combined chemically.
    compound
  22. A variation of an atom or atoms based on the loss or gain of an electron.
    ions
  23. A hot gas whose matter is broken into charged particles.
    plasma
  24. Greek word from which the word atom is derived. Means "indivisible."
