Symbol- Pt
What is the History of
Platinum?
Discovered by miners in 1500’s - thought it
was worthless
1557- Julius Scaliger described it
1748 - Antonio de Ulloa named Platinum
“Platina”- little silver in Spanish
Why is Platinum Important?
Uses - expensive jewelry, containers for
chemical experiments, automobiles,
experiment containers because of it’s high
melting point
Interesting Facts
Platinum is very dense
Cubic ft. of platinum - more than 1,300 lbs.
Platinum found usually in form of nuggets,
grains
Two large producers of Platinum- Russia,
South Africa

Conclusion
Over the weeks, I have learned a lot about
the element called platinum…
I think one of the most awesome things
about this metal is that it is often found
mashed together with other elements and
metals!
I also think it is interesting that it was
called rock by miners because platinum
rocks found in mines sometimes look like
any other rock
