1 Chlorine ions are colored yellow in the VRML model. 2  Sodium (Na +) and potassium (K +) are positive ions. 3  They are found on both sides of the membrane. 4  Na + ions are in greater concentration outside the neuron whereas K + ions are more concentrated inside the neuron. 5  Na + ions are colored pink in the VRML model.
