Physical Chemistry Polarization Repolarization

"1. When considering nerve impulse generation across a cell membrane, potassium ions (K+), sodium ions (Na+) and calcium ions (Ca++) are the ions most involved in this process. By definition these ions are defined as follows: a. Potassium, K+, is a monovalent anion and is the major intracellular ion; Sodium, Na+, is a monovalent cation and is the major extracellular ion, and Calcium, Ca++, is a divalent cation found mainly outside of the cell. b. Potassium, K+, is a monovalent cation and is the major extracellular ion; Sodium, Na+, is a monovalent anion and is the major intracellular ion, and calcium, Ca++, is a divalent cation found mainly outside of the cell.
