Atoms bond to form molecules. Which structures or regions of the

atoms interact in these bonds?

electric fields of particles with positive charge
electric fields of particles with no charge
electric fields of particles with opposite charges
electric fields of particles with negative charge

The structures or regions of the atoms that interact in bonds are the electric fields of particles with opposite charges. This interaction occurs between atoms through the attraction of positively charged particles to negatively charged particles, leading to the formation of chemical bonds.
