Introduction to ionic bonding

The movement of sodium and potassium ions back and forth through the cell membranes gives rise to electrical impulses and nerve transmissions within the body. This can become disrupted with increasing dehydration. 

You will already realize from earlier chapters that, for an atom to gain stability when it forms a compound, it tries to gain or lose electrons to make its outer electronic 

Complete transfer of the single electron from sodium to chlorine 

Sodium now has a positive charge because it has lost one of its electrons but still retains the 11 positive protons 

Chlorine ion is now negatively charged, 2.8.8, as it has gained one extra electron but still only has its original 17 protons

This chapter assumes that we know about energy (Section A) and the ideal gas law (Chapter 4). Some of the interpretations refer to intermolecular forces (Sections 4.14 and 5.1-5.5). The material here builds on the introduction to ionic bonding and bond strengths in Sections 2.1, 2.2, 2.16, and 2.17.
