History

History
The element Yttrium was discovered by Johan Gadolin in year 1794 in Finland. Yttrium derived its name from from Ytterby, Sweden
The element Protactinium was discovered by William Crookes in year 1913 in Germany and United Kingdom. Protactinium derived its name derived its name from from the Greek protos, 'first', and actinium, which is produced through the radioactive decay of protactinium
