Potassium

Potassium(K) is the 8th most abundant elements in the Earth’s Crust and it makes up roughly 2.1% of the Earth’s crust. Potassium is an alkali metal and is a soft and metallic solid with a high electrical and thermal conductivity. Its atomic number is 19 and was found by sir Humphry Davy in 1807 after using a process called electrolysis on potash (potash is an alkaline potassium compound).
In nature, potassium is difficult to obtain in its pure metallic state. It is usually found has a caption. A caption is when a metal loses a few electrons and becomes positively charged. Potassium captions in this case, lose on electron. Potassium can also be obtained
