Potassium is a Group 1 alkali metal element (atomic number 19) that plays a central role across multiple scientific topics, particularly in chemistry, physiology, and geoscience. Chemically, it is highly reactive, forming predominantly +1 cations that participate in ionic bonding and serve as key charge carriers in aqueous and solid-state environments. In biological systems, potassium gradients across cellular membranes are essential for maintaining membrane potential, driving action potentials, and regulating osmotic balance. In geoscience and environmental studies, potassium isotopes contribute to radiometric dating (e.g., K–Ar systems) and nutrient cycling. Research topics involving potassium span electrolyte transport, ion-channel biophysics, soil fertility, and materials science.
Building on their pioneering 2018 research into how some of the body's cells, such as neurons and cardiac tissue, communicate via ions that flow through cellular channels, chemists at the University of Massachusetts Amherst ...
