So that means that this nuclei will exert a force on this electron and this force will be equal to the force that this nuclei nucleus exerts on this electron. So this electron will pull this or this proton will pull this electron with the same amount of force that this proton will pull on this electron. So there will be an equal distribution of charge. These electrons will be found equidistant between these two nuclei. Distance will be the same exact. And this only occurs when we have the same amount of protons found in the nucleus.
