Tungsten
Pronounced: TUNG-sten
Scientist are still slightly confused about Tungsten because Tungsten was said to be discovered before 1783. Carl Willhem Scheele "discovered" Tungsten in 1781 from an accident involving Scheelite. He made it melt into acid and other people then told him that if he reduced the acid then he could make a metal out of it. Instead of him doing that, two brothers did what Scheele wanted to do. Their names being Fausto and Juan Jose de Elhuyar. They discovered tungsten 2 years after Scheele did the accident. The other theory is that a chemist by the name of Peter Woulfe discovered Tungsten in 1779 from a mineral called Wolframite. Wolframite is in fact the mineral that obtains Tungsten so in fact Peter Woulfe could have discovered Wolframite.
This shows where Tungsten was created. As you can see it was created in Spain.

Why I think Tungsten is Important

Why I think Tungsten is important is very simple. Tungsten is used in the wiring of lightbulbs. The wiring in a lightbulb is obviously important so if we didn't have Tungsten there would be no wiring which would mean no light and light is extremely important to have in a home. Maybe there are candles but its not an efficient way or source of light. Also the reason it is used in lightbulbs is because of its high melting point of (3,422℃, 6,192℉).
