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 Curium was discovered by Glenn T. Seaborg in year 1944 in United States. Curium derived its name derived its name from from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium
