Where was platinum found? 2019sbuti https://padlet.com/2019sbuti/platinum_/wish/304844858 It was found in 1557 by Julius C Scaliger. He discovered it in mines in between Panama and Mexico. When they saw it they found out that no amount of heat or fire that they could produce could melt it. Later in France 1783 a chemist found a workable way to use it, and they were able to use for many things.

Together they are mostly found in alluvial deposits but also found in the U.S.A. around ural mountains.]]> 2018-11-15 15:26:12 UTC https://padlet.com/2019sbuti/platinum_/wish/304847340 How rare is platinum? 2019sbuti https://padlet.com/2019sbuti/platinum_/wish/304848273 It is very rare and can cost $13000 in pure form for a 100g

Nickel and palladium also have the same amount of electrons (metal family)]]> 2018-11-15 15:33:13 UTC https://padlet.com/2019sbuti/platinum_/wish/304851636 What and why is platinum in its column 2019sbuti https://padlet.com/2019sbuti/platinum_/wish/304852379 Platinum falls into row 6. It is the row for its atomic orbitals. The number of atomic orbitals for platinum also include iridium, osmium, and rhenium which are there because they all of the same atomic orbitals as platinum 
    (metal family )
