Chemistry Quiz - Metals
1. What are the chemical symbols for the metals aluminium,iron,titanium,magnesium,zinc,copper,tin,lead,tungsten,silver,uranium and gold in order?
A Al,I,Ti,Mg,Zi,Co,Tn,Ld,Tu,Si,U,Go
B Al,Fe,Ti,Mg,Zn,Cu,Sn,Pb,W,Ag,U,Au
C Al,Fe,T,Mg,Z,Co,Tn,Pb,Tu,Ag,U,Au
2. Most metals have similar physical properties of:
A yellow colour, shiny lustre, very hard
B low melting point, good electrical conductivity, silver colour
C shiny lustre, good heat and electrical conductivity, and high melting and boiling points
3. A metal which is an exception because it has a low melting point of -39 degrees Celsius is:
A sodium
B oxygen
C mercury
4. Two very reactive metals which have densities less than that of water and can therefore float are:
A sodium and potassium
B lead and copper
C aluminium and lead
5. A metal that is a good electrical conductor and is very ductile (can be pulled into a wire) is:
A mercury
B calcium
C copper
6. The reason why metals are usually good electrical conductors is because:
A their atoms are loosely packed and in no particular arrangement and are able to move freely
B metal ions form a lattice surrounded by a "sea" of free electrons
C metal atoms form long lines that allow little movement
7. The mineral from which aluminium is extracted is:

C bauxite
8. The mineral from which magnesium is extracted is:
A magnesite
B haematite
C gold

Coxygen and metallic oxides
11. When a metal corrodes in water, they form:
Asalt and water
Brust and carbon dioxide
Cmetal hydroxide and hydrogen
12. The activity series of metals lists metals from:
Amost abundant to least abundant in the earth's crust
Bmost reactive to least reactive
Cleast used to most used in man-made products
13. The general name given to a mixture of metals or metals and non-metals such as carbon and silicon is:
Asacrificial protection
Bmetal carat
Can alloy
14. The refining of a pure metal in a blast furnace is called:
Aslag
