Differbetween
Neutrons are large and made out of multiple other particles and form part of the atomic nucleus, while neutrinos are tiny, single particles with almost no effect.

What are the 3 types of neutrinos?
Perhaps the most important thing to know about neutrinos is that they come in three types, or flavors:
- electron neutrino (νe)
- muon neutrino (νμ)
- tau neutrino (ντ)
What is the difference between an electron and an electron neutrino?
Neutrinos are one of the fundamental particles which make up the universe. ... Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons.
What is the purpose of neutrinos?
Neutrinos play a role in many fundamental aspects of our lives; they are produced in nuclear fusion processes that power the sun and stars, they are produced in radioactive decays that provide a source of heat inside our planet, and they are produced in nuclear reactors.
What do neutrinos make up?
A neutrino is a very small piece of matter. ... Neutrinos however fall into a category called leptons. Leptons are also fermions, and together with quarks make up matter. The difference between leptons and quarks, is that leptons exist on their own, where quarks combine to form baryons.
Can neutrinos travel faster than light?
Five different teams of physicists have now independently verified that elusive subatomic particles called neutrinos do not travel faster than light. ... The OPERA team made headlines after they suggested neutrinos traveled 0.002% faster than light, thus violating Einstein's theory of special relativity.
Are neutrinos dangerous?
Of all the elementary particles that we know of, neutrinos are the least harmful of them all. ... All charged particles, like electrons, protons, etc do interact and in sufficient quantities can be harmful. Even some neutral particles like gamma rays or neutrons can be harmful since they have stronger interaction rates.
What is the smallest particle?
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
Is a neutrino a particle?
A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. ... Both the muon and the tau, like the electron, have accompanying neutrinos, which are called the muon-neutrino and tau-neutrino.
Are neutrinos dark matter?
Neutrinos could be key particles to unravel the nature of the dark matter of the Universe. On the one hand, sterile neutrinos in minimal extensions of the Standard Model are excellent dark matter candidates, producing potentially observable signals in the form of a line in the X-ray sky.
Do neutrinos have energy?
The energy of a neutrino depends on the process that formed it. Because neutrinos have no charge, there's no way to use electric fields to accelerate them and give them more energy, the way scientists can do with particles such as protons. ... But there is a big range of neutrino energies.
Where are neutrinos found?
Neutrinos are everywhere. They permeate the very space all around us. They can be found throughout our galaxy, in our sun and every second tens of thousands of neutrinos are passing through your body. But there is no need to become alarmed for these tiny particles barely interact with anything.
How do we detect neutrinos?
A neutrino is able to react with an atom of gallium-71, converting it into an atom of the unstable isotope germanium-71. The germanium was then chemically extracted and concentrated. Neutrinos were thus detected by measuring the radioactive decay of germanium.
