Is photon smaller than neutron

Answer 1

Photons are larger than electrons. Electrons are "point particles" which means while they have mass, they do not have any determinable heighth, width or depth. Photons, on the other hand, most definitely have a specific volume.

Correction:

A fairly common misconception so I'm leaving the original answer in place. Under quantum mechanics we can observe a photon as a particle or a wave, just as we can an electron. We happen to find it easier to think of electrons as particles and photons as waves but in reality both can be either, it just depends which properties we measure. Both particles, in fact all fundamental ones, are pure points - at least down to the superstring level where all bets are off. Quantum mechanics makes the position of the particle uncertain, it does not mean the particle itself is bulked up.

Answer 2

They are both fundamental particles and therefore points. Points cannot be bigger or smaller than other points.

Quarks are never found alone but many common subatomic particles are not elementary but composed of two or three quarks. Protons and neutrons which make up the nucleus of an atom are themselves composed of three quarks. Such composite particles may be thought of as a small cloud of point particles or as a single ball with a particular diameter.

Photons, on the other hand, don't stick together.

Answer 3

Opinion 1: No. A quark is a nano-sized part of an electron.

Opinion 2:

Since the Quarks are thought to be the building blocks of atoms...

No. I do not find this to be logical. There is more to it than this though.

Experiments have been run in order to try to figure out the size of an electron. None of which have been successful to my knowledge as of today.

The electron is thought to be a fundamental particle. A Quark is thought to be a fundamental particle. What is smaller? This basketball or that basketball?

They might even be the same size.

Fundamental particles does not have to be the same size but we can not say for sure they are not. You pull out your ruler and try to measure them.

What is logic when we try to apply this to particles we simply have no method of taking a picture of, let alone actually measure.

Science have made different models in order to try to understand how things works. The model of atoms and electrons etc... It is a proven model. It works. It is however only a simplistic and crude model used to explain cause and effect. Even though we imagine how atoms behave and electrons orbiting these atoms, this is only a model and can not be 100% proven as of today. This is why we try to figure out what the smaller particles making the atoms are.

Due to the size and limitations of electronics and mechanics due to size, this is a problem we most likely will never be able to figure out with factual proof.

It can most likely be explained by the following question:

How can we accurately measure the size of a virus with a 30 cm ruler?

Answer 4

YES!!!?

Photons are mass-less particles. The wave nature of photons makes it hard to define a size for a photon. You could (sort of) say that a photon is smaller than a neutron because it is mass-less. Analyzing the size of a photon gets tricky due to the quantum nature of photons.

Answer 5

They are the same size, All fundamental particles are points.
