You haven't really asked a question, but the subatomic particle you've referenced is either a neutron, or a proton. I say that since the mass of those two particles are:
proton = 1.6726 x 10^-24 grams
neutron = 1.6740 x 10^-24 grams
both of which round to 1.7 x 10^-24 grams which is 1.7 x 10^-27 kilograms.
