221:. It would be more informative if there were some contours showing e.g. 'The electrons have a 90% likelihood of being located within this circle'. Also, if that gradient represents the cloud, then what do the gradients on the proton and neutron represent? They certainly aren't probability densities; rather, they seem to be simple graphical decorations. Also, nowhere in the picture or the caption is there any indication that the electron shell contains 2 electrons... this is a pretty basic fact.

I don't understand the purpose of this image. You cannot even see the sizes of the protons/neutrons relative to the electron cloud because they are not even shown on the picture for obvious reasons. So what exactly are you trying to convey with this image? I feel like I'd get just as effective of an

accurately depict the actual probability density at that point. However, there is a more serious problem. By the author's own admission, the depiction of the nucleus is completely wrong; in reality the four nuclear particles are superimposed and create a spherical cloud similar to the electrons. I

I actually don't think it does have much EV. There is a wealth of information you could convey in a picture of an atom. This image only illustrates one fact, and it does it poorly. Since you can't see the nucleus at all in the zoomed-out image, having an insert magnification doesn't do much to

If this is nearly infinite magnification, then I don't think there should be any red cloud visible at the centre of the atom.
