WHO DISCOVERED POTASSIUM:
SIR HUMPHRY DAVY
WHEN WAS IT DISCOVERED:
IN 1807
HOW WAS IT DISCOVERED:
POTASSIUM IS A COMPOUND ITSELF SO YOU HAVE TO EXTRACT POTASSIUM HYDROXIDE TO GET POTASSIUM. POTASSIUM IS NEVER FOUND FREE IN NATURE ITSELF. POTASSIUM COMES FROM A SUBSTANCE CALLED POTASH. POTASSIUM ISN'T POTASSIUM UNLESS IT'S BONDED WITH OTHER ELEMENTS.

POTASSIUM IS AN ALKALI METAL
WHY WOULD THIS ELEMENT BE CONSIDERED IMPORTANT?:
THIS ELEMENT WOULD BE CONSIDERED IMPORTANT BECAUSE IT IS IN OUR DIET WE NEED POTASSIUM TO STAY HEALTHY. FOODS THAT HAVE POTASSIUM IN IT WOULD BE INSTANT COFFEE, RAISINS, NUTS THOSE ARE JUST SOME OF IT. WE ALSO CONSUME ABOUT 7 GRAMS A DAY. IT IS ALSO FOUND IN FERTILIZER , OF COURSE UT'S REALLY IMPORTANT NOW RIGHT?
