|
list the properties of metals. |
luster, malleable, ductile, higher densities |
|
|
what is conductivity |
ability to move heat or electricity |
|
|
list the properties of the transition metals |
hard shiny, solid at room temperature high melting points and high densities good cconductors of heat and electrcity, malleable, less reactive |
|
|
describe the reactivity of metals as you look across the periodic table from left to right |
the metals are most reactive in group 1. as you look across the periodic table from left to right they become less reactive |
|
|
list the properties of nonmetals |
dull, brittle, most are gases at room temperature, bromine is the only liquid, poor conductors of heat and electicity, low densities |
|
|
at room temperature, more than half of nonmetal elements are found in which state? |
gas |
|
|
which group contains elements that do not ordinarily from compounds. |
group 18, the noble gases |
|
|
which family contains the elements fluorine and chlorine, which are very reactive nonmetals? |
halogens, group 17 |
|
|
what are metalloids? |
elements that have properties of metals and nonmetals |
|
|
where on the periodic table can metals be found? nonmetals? metalloids? |
metals- left side nonmetals- right side metalloids- along the zig zag line |
|
|
list the properties of metalloids. |
solid at room temp. brittle, semiconductors, can conduct electricity under some conditions, somewhat reactive |
|
|
what is a semiconductor |
conducts electrcity under some conditions, but not under others |
