#Unit 1. Molecules and their Interaction Relevant to Biology
As atom "A" approaches, the electrons of atom "B" will be attracted by the positive end of atom "A". As a result, the electrons of atom "B" will migrate to the left side and make the left side slightly negative. This phenomenon can be explained by
