Copper is a pure element, (Cu) not a mixture or compound.Copper is an element. So, it is only made up of one mineral: copperYou can make a vacuum cleaner. Coins, telephones, coins, cell phones, and washing machines
Streak test because minerals can vary in color, size and shape but their streak color will always be the same for that specific mineral. Calcite comes in many shapes and colors, but its streak is always white.

Colour is least reliable property to recognise mineral in field. but is best for studying and recognising mineral in lab under Polarized light microscope (PLM). <br /> let us take a simple example of quartz and calcite both have nearly same colour range so just by observing colour you can not give a guess but by applying different field techniques at same time we can distinguish them as calcite can be scratched by nail but quartz will not be scratched. <br /><br /> (Allah Knows the Best) <br /><br /> One interesting thing is that colour is most deceiving thing in this world. About 90% of frauds are done by colours. it I think I need not to explain it. :-) <br /><br /> CHEERS
you should use a streak test this will use color streaks to show metal should be white non metal will be a darkish color like the material

Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the periodic table lying in the diagonal metalloids in the p group. The metallic and nonmetallic properties may be, for example, that it is grey and shiny like a metal but it may also be brittle and not conduct heat and electricity like a nonmetal.
