Summary

Using the criterion that for negative monoatomic ions withN electrons, the location of minimum in the electrostatic potentialV(r) gives an approximate estimate of ionic radii,rm. Calculations of the latter are reported for quark atoms with fractional nuclear chargesZ=N\(\frac{1}{3}\) andN\(\frac{2}{3}\), respectively. Quark atoms withN=1−10, 18 and 36 have also been considered.
