Potassium ions are the most diffusible ion in the membrane potential because of the presence of leak channels that allow potassium to move easily across the membrane. This creates a concentration gradient that drives the movement of potassium ions into and out of the cell to establish the resting membrane potential.
The Nernst equation is used to calculate the equilibrium potential for a particular ion. It takes into account the ion concentrations inside and outside the cell, as well as the charge of the ion, to determine the membrane potential at which there is no net movement of that particular ion across the membrane.

I^- is the most common ion of Iodine.
The most common Selenium ion is Se2- the selenide ion. It is in the same group as oxygen and its most common ion in the oxide ion O2-.
The fluorine ion (F-) is known to be one of the most chemically reactive ions due to its high electronegativity and ability to readily accept electrons to achieve a stable electron configuration. It forms strong bonds with other elements, leading to highly reactive compounds.
The electric potential energy of an ion is the energy stored in the electric field surrounding the ion due to its charge. It is directly proportional to the ion's charge and the electric potential at the location of the ion. This energy can be calculated using the formula: U = qV, where U is the electric potential energy, q is the charge of the ion, and V is the electric potential at that point.
The Nernst potential refers to the reversal potential of the membrane potential at which there is no net flow of a particular number of ion from one side of the membrane to another.
The Nernst equation is used to calculate the equilibrium potential for a particular ion. It takes into account the ion concentrations inside and outside the cell, as well as the charge of the ion, to determine the membrane potential at which there is no net movement of that particular ion across the membrane.
