I was thinking about energy scale, measured in eV and i've found this grafic. Now, roughly speaking, if we think energy as a mass, we can measure it by eV. Then from the grafic we have for example electron is lighter than proton, which is lighter than higgs, and so on.

But, what if we think about it in lenght term? Electron is smaller than proton, and that's ok. So this means that higgs should be bigger than proton.

And so, why this image is putting atom (100 eV) before electron (0.5 Mev), for example?

Thank you
