What is the size difference between protons electrons and neutrons?

Answer 1

Protons and neutrons have approximately the same size and mass. A neutron is slightly heavy than a proton to be more accurate. In general we can say that they both have same mass which is 1 amu. The actual difference is 2.31 x 10-30kg), but are different charge (+1 and zero respectively).

Also, an electron and positron have the same mass and size and more generally, any particle will have the same mass as its antiparticle.

Answer 2

Protons and Neutrons are the same size, Electrons, which are on the outside. Are the smallest of them all. Hope this helps.

Answer 3

No, they are not. Neutrons are as big as protons and electrons are smaller than both protons and neutrons

Answer 4

Proton: 1,007 276 466 77(10) Atomic Mass units (u)

Neutron: 1,008 664 915 6 (6) atomic mass units (u)

Electron: 5,485 799 094 3(23).10-4 atomic mass units (u)

Answer 5

mass of an electron=9.109382*10^-28

proton=1.672622*10^-24

neutron= 1.674927*10^-24

Answer 6

they are the same size, but the mass of a neutron is roughly the sum of the mass of a proton plus the mass of an electron.

Answer 7

The proton and the neutron are approximately similar in size but the electrons are much smaller.

Answer 8

Neutrons and protons are similar in size. but protons are smaller than protons and neutrons.
