Atom Part Radii: Electron, Proton, Neutron

In summary, the size of an electron is approximately 0.0000000000000000000000000000000001 meters, or 0.00000000000000000000000000000000000004 inches. It is much smaller compared to the sizes of protons and neutrons, which are approximately 0.0000000000000000000000001 meters or 0.00000000000000000000000004 inches. These sizes are measured using a unit called the femtometer, and they can change depending on energy levels and interactions with other particles.

Do anybody know the radius of an electron, proton, or neutron? I understand there are smaller things like quarks, and everything, but as a general size, does anybody know the radius of these parts of an atom?

Electron and quarks are so far pointlike particles. The radius of the proton and/or the neutron depends on how you actually define such a thing. Typical values for the radius of nucleon are of the order 1 fm, which is [tex]10^{-15}[/tex] m.

1. What is the size of an electron?

The size of an electron is approximately 0.0000000000000000000000000000000001 meters, or 0.00000000000000000000000000000000000004 inches.

2. How does the size of a proton compare to the size of an electron?

The size of a proton is much larger than that of an electron. It is approximately 0.0000000000000000000000001 meters, or 0.00000000000000000000000004 inches.

3. What about the size of a neutron?

The size of a neutron is similar to that of a proton, being approximately 0.0000000000000000000000001 meters, or 0.00000000000000000000000004 inches.

4. How are the sizes of these particles measured?

The sizes of these particles are measured using a unit called the femtometer, which is equal to 0.000000000000000000000001 meters.

5. Do the sizes of these particles change?

Yes, the sizes of these particles can change depending on various factors such as the energy levels they are in and the interactions they have with other particles.
