Use of Elements and Why?
I just want to know what the following elements can be used as, and why it could be used.
Lead
Chromium
Carbon (graphite)
Silicon
Titanium
Tungsten
Thanks so much in advance
I just want to know cos i saw a TV show that said all elements could be used for something useful.
i meant for each one what can it be made into,
e.g. gold can be made into jewelry
and also what is a property of the element that enables it to be made.
Lead – malleable and resistant to corrosion, thus, it is used in building construction like lead paint. Lead is used in batteries and bullets too.
Chromium – high corrosion resistance and hardness. Added to steel with nickel to form stainless steel. The mineral chromite also contains chromium and this mineral was used in pigments eg. paint.
Carbon – Graphite has weak bonds which enables us to create pencil lead. I don’t know why pencil lead is called lead when the graphite is actually carbon. As graphite has weak bonds, it can be used as a writing material because when we write, marks are left on the surface.
Silicon – Semiconductor, remains so at high temperatures and thus it is very useful. Used as computer chips. Other forms eg. silica are components in glass, cement and ceramics. And of course, silicones has properties such as impermeability to water, flexibility and resistance to chemical attack. This is useful and makes the famous breasts implants, contact lenses and explosives.
Titanium – Really strong. Has corrosion resistance, and the highest strength-to-weight ratio of any metal. Thus, produce strong lightweight alloys for aerospace (planes), jewelry, mobile phones, dental instruments, medical prostheses etc.
Tungsten – Very high melting point, thus combined with other metals, when it becomes an alloy, it can be used for lightbulb filaments and x-ray tubes.
I hope these help 
I had to do this for chem and wiki helped a lot (:
