To convert from one resonance structure to another, only electrons can be moved

Explanation:

The resonance structure is known as the molecular bonding system in which a hybrid, called resonance, is formed from two or more Lewis structures that have different electronic distributions. The degree of similarity and the number of resonant structures measure the stability of the compound in which it occurs.

In organic compounds, there are cases in which, from the formula recorded as a function of the Lewis structures, it is impossible to determine with precision the exact structure of a molecule. Thus, in a nitrile chloride molecule, there exist two alternative structures distinguished only based on the positions of its electrons, but not on those of its atoms.
