PotassiumAn element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells.
Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. The concentration differences of these charged particles causes a difference in electric potential between the inside and outside of cells, known as the membrane potential.
The balance between potassium and sodium is maintained by ion pumps in the cell membrane. The cell membrane potential created by potassium and sodium ions allows the cell generate an action potential—a “spike” of electrical discharge.
The ability of cells to produce electrical discharge is critical for body functions such as neurotransmission, muscle contraction, and heart function.
Potassium is also an essential mineral needed to regulate water balance, blood pressure and levels of acidity.

IodineIodine is a chemical element with the symbol I and atomic number 53.
The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.
The element was discovered by the French chemist Bernard Courtois in 1811. It was named two years later by Joseph Louis Gay-Lussac from this property
The dominant producers of iodine today are Chile and Japan. Iodine and its compounds are primarily used in nutrition.
