Elements are listed according to their atomic _____________________.
Elements in the same row across belong to the same ____________________.
Elements in the same up-and-down column belong to the same
________________.
Part Ten: Properties of Metals. Know the following:
 Metals are malleable (you can hammer or press a shape into it
without breaking it.
 Metals are solid except for mercury
 Metals are good conductors of heat
 Metals have a shiny metallic luster
 Metals are good conductors of electricity
 Metals are silver-gray, except for gold and copper
Part Eleven: Properties of Nonmetals. Know the following:
 Nonmetals are found in all states (solid, liquid, gas)
 Nonmetals come in all different colors or are invisible
 Nonmetals are poor conductors of electricity. (They usually insulate,
or keep in the heat)
 Nonmetals have no metallic luster
 Nonmetals are not malleable, they will break
 Nonmetals have odors.
