AFM tip more sensitive than a single atom

sometimes a pile of atoms looks like a bunch of round things Chemists note these form ordered structures Thus a Face centered cubic arrangement has a different density than a body centered cubic arrangement

If we ignore that arranging to just look at amorphous density then we find some elements have equal densities Zn as well as Cr have density 7.14

thus whatever the actual preferred crystal form of a Zn or Cr crystal is if we put just one Zn or Cr atom at the tip or side of an ordered crystal made of the different element then all of the reacting that atom does will be from Nucleus charge rather than actual atomic radius difference

It appears that this gives an AFM tip the ability to view things with higher resolution than an AFM tip of just one element or of a crystallized compound

From a nanotechnological point of view with an amorphous equidistant mass the density is reminiscent of which atoms have an average similar radius yet the actual electronegativity of the atom as well as that atoms quantum conduction areas is what will react to the thing being characterized

rather than a bunch of atoms flexing to modify measured e- its just one atom flexing as the tip nears an object

Now there is a peculiar thing about this: I got my density numbers from wolframalpha so its possible they used a copy of the CRC handbook numbers for say a chunk of Cr with FCC crystals at STP as well as a chunk of Zn with BCC crystals at STP or its possible they calculated amorphous density from AMU times atomic radius

note that atomic radius varies irregularly with atomic mass thus Gallium might actually be more dense than Germanium even though Germanium has more protons plus neutrons; generally if its a liquid near STP like Ga or Br it has a tighter nucleus

My idea works if they did AMU times atomic radius yet they have the densities of things like nitrogen as .0001 with Zn at 7.14 thus I think the densities are a chunk of element at STP

I still think the idea works its just I don't know which elements actually have identical amorphus density from AMU times atomic radius
