Potassium is called "K" because its chemical symbol is derived from the Medieval Latin word kalium.
Here's a more detailed explanation:
-
The name potassium comes from the English word potash. Potash refers to potassium compounds extracted from wood ashes and leached in a pot.
-
However, the chemical symbol for potassium is K, which is not derived from the English name.
-
The symbol K comes from the Medieval Latin term kalium, which was also used to refer to potash.
-
The origin of "kalium" is thought to be from the Arabic word qali, meaning alkali. Alkalis are a group of chemical compounds, including potassium hydroxide, that neutralize acids.
In summary, while the element is known as potassium in English, its chemical symbol, K, is derived from the Latin word kalium, which is related to the historical production of potash and its alkaline properties.
