In the case of potassium, the letter "K" represents it on the Periodic Table. Updates? If correct case (Secure PayPal), Try3Steps is licensed under a Creative Commons Attribution-NonCommercialShareAlike4.0 International. Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. It is light enough to float into water with which it reacts instantly to release hydrogen, which burns with a lilac flame. Use correct case for element symbols. [102] In 2005, about 93% of world potassium production was consumed by the fertilizer industry. Are We Wrong To Think We're Right?

Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite. Atomic mass Density (near r.t.)

To specify one or more of a given atom, use a A form of vitamin K known as phylloquinone (vitamin K1) is synthesized by plants. This reaction is exothermic and releases sufficient heat to ignite the resulting hydrogen in the presence of oxygen. Its presence is of great importance for soil health, plant growth and animal nutrition. Phone: +971 4 429 5853 e-mail:, Copyright © 1998-2020 Lenntech B.V.

Please follow the steps below to Chemical Formula Search Help Rules for chemical formulas (Back to search) Enter a sequence of element symbols followed by numbers to specify the amounts of desired elements (e.g., C6H6). A very few elements have symbols which appear to have no relationship with their names. Inhalation of dust or mists can irritate the eyes, nose, throat, lungs with sneezing, coughing and sore throat.
