none of the above
2) Which of these is NOT a physical property used to classify metals, nonmetals, and metalloids?
A
texture
B
luster

it's a poor conductor of electicity
B
Its soft and malleable
C
It can be pulled into thin wires
D
It has a shiny surface
4) A student is trying to decide if an element is a metal or a nonmetal. What should the student do?
A
Find the element's melting point
B
Measure the element's conductivity
C
Find the elements density.
5) Where on the Periodic Table are the metalloids found?
A
on the right
B
along the stair step
C
on the left
D
along the bottom
6) What are the physical properties we use to classify metals, nonmetals, and metalloids?
A
reactivity, smell, and density
B
luster, conductivity, and malleability
C
physical state, hardness, and mass
D
explosive, corrosive, and reactive
7) A certain element, when pounded with a hammer, doesn't break apart but forms thin sheets. It also conducts electricity very well. The element is most likely a
A
nonmetal
B
metalloid
C
none of the above
D
metal
8) Which group of elements has, in general, higher melting and boiling points?
A
metals
B
none of the above
C
nonmetals
D
metalloids
9) What would be a good element to make an electrical wire out of?
A
Carbon because it is a solid at room temperature
B
Copper because it is a metal and conducts electricity well.
C
hydrogen because it is a nonmetal and conducts electricity well.
10) What is luster?
A
the way a surface reflects light
B
the way a substance can be shaped by hammering
C
the way a substance conducts electricity
11) Ther are only a few nonmetals that conduct electricity
A
True
B
False
12) What would be the best way to determine if an element is malleable or not?
A
see if it conducts electricity
B
see if it sinks or floats
C
try to hammer it flat.
D
shine a light on it.
13) If I student wanted to find an element that was a good conductor of electricity, had a shiny surface, and was soft and malleable, where on the Periodic Table would they look?
A
with the metals
B
they won't find it on the periodic table.
C
with the gasses
D
with the nonmetals

A
metals
B
metalloid
C
nonmetals

A
potassium is a metal and polonium is a metalloid
B
they are both metals
C
they are both nonmetals
D
potassium is a metalloid and polonium is a metal
