Yttrium

Located in Group 3 and Period 5 of the Periodic Table is the element used before flat screen television in Cathode Ray Tubes, it is the well - famous Yeetrium! ( Yttrium )

Old TV

In 1787, Karl Arrhenius came across an unusual black rock in an old quarry at Ytterby, near Stockholm. He thought he had found a new tungsten mineral. To prove his hypothesis, he passed the specimen over to Johan Gadolin in Finland.

Until 1794, Gadolin announced that it contained a new 'earth' which made up 38 percent of its weight.

In 1828, Friedrich Wöhler isolated Yttrium by synthesizing it's chloride and heating it with Potassium Metal. Yttrium was then isolated.

How did Yttrium got it's name?

Yttrium got it's name from a city called Ytterby, located at Sweden. As for why, Ytterby is the city where Yttrium was found. Besides, Yttrium is one of four if the elements to be named after Ytterby.
