Arsenic was discovered by Albertus Magnus in
Germany in 1250.
Arsenic is thought to have been
found when Albertus Magnus
warmed soap along with orpiment.
This experiment caused the arsenic
to be confined within the new
mixture.

3s2p6d10 4s2p6d10 5s2p1.
Abbreviated Electron Configuration[Kr]5s24d105p1.
Common uses-Used to coat high speed
bearings, in solar cells, mirrors, regulators
in nuclear power, photo cells, transistors
and blood & lung research. Also used in
low-melting point alloys for safety devices.
Indium was discovered by
Ferdinand Reich, Hieronymous
Richter in Freiberg Germany,1863
Reich and Richter had been
looking for traces of the element
thallium in samples of zinc ores. A
brilliant indigo line in the sample's
spectrum revealed the existence of
indium.
