(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.

Octet rule
atoms are more stable when they have eight electrons in their outermost electron shell
discovered the electron; disproved atomic theory that assumed atoms were indivisible

electrons found closest to the nucleus
ductile
can be drawn into thin wires
Elements that are
