[115][116], Another example is potassium cobaltinitrite, K3[Co(NO2)6], which is used as artist's pigment under the name of Aureolin or Cobalt Yellow. [119] The ternary alloy of 12% Na, 47% K and 41% Cs has the lowest melting point of −78 °C of any metallic compound. 8 years ago. I. IceWaterLightningFireEarth. a. potassium. Meaning of Potassium. For example: – Symbol ‘K’ represents the element potassium and also represents one atom of potassium. Neutral atoms have a charge of zero, so no superscript is given. The formula for an ionic compound must contain the same number of positive and negative charges. e. beryllium. Potassium metal reacts vigorously with all the halogens to form potassium halides. Many common fire extinguishing agents, including water, either are ineffective or make a potassium fire worse. An abnormal increase of potassium (hyperkalemia) or decrease of potassium (hypokalemia) can profoundly affect the nervous system and heart, and when extreme, can be fatal. Potassium bromide (KBr) was formerly used as a sedative and in photography.
