4.  Which of the following statements is true?
feldspar is harder than apatite and softer than quartz.
topaz is harder than felspar but softer than fluorite
5.  Which of the following statements is true?
6.  This student is testing a quartz crystal for a certainproperty.  What property are they testing?
streak
malleability
hardness
luster
metal
nonmetal
metalloid
7.  Mrs. Ruble found these pieces of material outsidewhile riding her dirt bikeone weekend.  She discoveredthey had luster and were very brittle.  She tested to see if they conducted electricity but found theydid not conduct electricityas good as copper wire.Mrs. Ruble thinks thismaterial is a______________.
8.  Mrs. Davis found this substance at school 
and was trying to determine if it was a metal, nonmetal, or metalloid. It has luster, conducts electricity, and is very malleable.  Mrs. Davisthinks this substance must bea___________________.
metal
nonmetal
metalloid
metal
nonmetal
Mrs. Ruble was conductinga test to see how this objectreacted to electricity.  Aftertesting it, she decided it was a very dull, very brittle semiconductor.This object must be a:
metalloid
The wire in this picture are 
made from a material that
is ductile and able to be
stretched into thin wires.
The material is most likely
a:
nonmetal
metalloid
metal
Mrs. Davis was examining the gas in a neon light.Upon examining the gas, she noticed it was light red,it was not malleable or ductile.  The gas is most likely a:
nonmetal
metal
metalloid
Mrs. Ruble found a piece of metal and is trying todetermine what is made of.  She weighed it on a scaleand found the mass to be 26.4g.  She found the volume to be 3mL. Calculate the density and help determine what the substance is made of.
Nickel
Steel
Mrs. Davis took some mineral samples and beganscraping them across a streak plate to see what color powder they left behind.  Mrs. Davis wastesting the minerals for:
conductivity
luster
hardness
streak
Mrs. Ruble measured the mass of two different minerals and found they had the same mass.Which statement is most likely true about theminerals?
they are made of the same stuff.
They have the same mass and volume.
They don't necessarily have the same density.
they are exactly the same.
Luster, density, malleability, ductility, are 
all examples of:
metalloids
chemical properties of matter
minerals
physical properties of matter
