13

metals (long list)

lower left corner of periodic table
good electrical and heat conductors
are malleable and ductile and lustrous
have hight tensile strength
are solid at room temperature (except Hg (mercury), which is liquid at room temp)

14

nonmetals (long list)

upper right corner of periodic table
are poor electrical and heat conductors
are brittle when solid and dull (not shiny)
are mostly gaseous at room temp but can be liquids (Br (Bromine)) or solids (C (Carbon), P (Phosphorous), S (Sulfur), Se (Selenium), I (Iodine))

15

metalloids or semimetals (long list)

located along "staircase" on periodic table
have characteristics of both metals and nonmetals
all solid at room temp
B, Si, Ge, As, Sb, Te
