1/11/2012 The 3 subatomic particles are protons, neutrons, electrons. List, in ascending order, the subatomic particles sizes and their charges.

In ascending order, the neutrons (no charge) are slightly bigger than the protons (positive charge). They are both bigger than electrons (negative charge). The sizes of Protons and neutrons are 10^-13 cm (approx. 1,5-2 fm). The electron may be 10^-17 m, but this is only a calculated value.
