History

History
The element Berkelium was discovered by Lawrence Berkeley National Laboratory in year 1949 in United States. Berkelium derived its name from from Berkeley, California, where the element was first synthesized, by analogy with terbium
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
