We know the charge and mass of a proton. What is its volume?
Mass of proton : 1,6726 x 10^(-27) kgVolume of a proton (~1.5×10−41 m³)Density of proton = 1.12 x 10^17 kg/ m^3Is it of any value in physics?
In the standard model, we have predictions that are based on why they have the mass they have, but the predictions soon manifest themselves into a strange paradoxical question: Why these certain masses, and not the other quantities? In quantum physics this is called the Heirarchy Problem
Yes, from this site. Is a proton the densest particle?
The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron.
Is the mass of a neutron = mass of proton + mass of electron + mass of antineutrino ?
