How big is a neutron?

Answer 1

its difficult to talk about size, when talking about such particles. Maybe someone will correct me, but my understanding is that electrons and protons have no size: we say they are point particles. They have a probability wave which shows where they are likely to appear, but I don't think they actually have a volume as, in the same way, a swimming pool or a car would have.

We can estimate the size of a nucleus, which consists of neutrons and protons, then divide that volume by the total number of nucleons, which would probably give a value of 10^-15m, but can you actually say that a free floating neutron has a volume? I don't know.

Electrons certainly dont. We say they are point charges.

Answer 2

Neutrons are subatomic particles that is one half of the nucleus of an atom. The mass of a neutron is measured to be 1 Atomic Mass unit, which is too small to see even with an electron microscope.

Answer 3

If you try to think about it in perspective:

If the size of an atom is the size of a stadium, the neutron would be about the size of a football.

It takes about 100 000 nuclei lined up in a row to reach across an atom.

That is very small, since we can't even see atoms without machines and microscopes.

Answer 4

Roughly the size of earth, give or take a bit. If they were much bigger they would rapidly become black holes. If much smaller they would not have become neutron stars, but would have stayed ordinary matter white dwarfs somewhat larger than earth.

Answer 5

A neutron is a subatomic particle with no net electric charge and a mass slightly greater than that of a proton. It is considered to be a point-like particle, meaning it has no definite size.

Answer 6

They are relatively the same size, therefore their relative weight is 1.

Answer 7

The diameter is approx 1.7*10-15 metres or 1.7 femtometres.

Answer 8

the size of a nucleus 10/34 6.89

Answer 9

Neutron mass/electron mass = 1 836
