Answer:
electron, proton, neutron
Explanation:
Mass of electron= [tex]9.1\times 10^{-31}kg[/tex]
Mass of proton [tex]=1.672\times 10^{-27}kg[/tex]
Mass of neutron [tex]=1.674\times 10^{-27}kg[/tex]
From the above we can see that the mass of neutron is highest and the second highest mass is of proton and electron has the lowest mass
So the correct order of the mass will be electron, proton,neutron
