If a negatively charged ion is more concentrated inside the cell, the forces required to balance the chemical gradient would be directed . Thus, the equilibrium potential for this ion would be charged.

If a negatively charged ion is more concentrated inside the cell, the forces required to balance the chemical gradient would be directed Inward. Thus, the equilibrium potential for this ion would be Positively charged.

Explanation:

The measurement of potential of resting membrane is distributed unequally in the form of ions or the charged particles, which are consist between both the cell's internal structure and external structure, by the membrane's changing permeability to various ion forms.

Like in most of the neurons the potassium and organic ions which are common in amino acids are present more in internal portion of cell than its outer portion. By comparison sodium and chloride ions are normally present in the cell externally at higher concentrations. This implies there are balanced gradients of concentration around the membrane for all the most concentrated forms of ions.
