For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready passage of larger potassium ions compared to the smaller sodium ...

Sodium and potassium ions attract the oxygen atom in water molecules. The water molecules surround the ions forming a "hydration shell." The radius of the hydration shell, ...

Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years.

Sodium-ion batteries are close to commercial viability, but potassium offers even better energy density — a critical factor ...
