Q. What is the neutron?

Answer:-

A neutron is a subatomic particle it's one of the building blocks of the atom. It has a mass of in relation to 1.675 x 10-27 kg. Its spin is + 1/2 along with that makes it a fermions. In addition it has no electric charge which is a distinctive feature. It is unbalanced when free in nature, and has a half life of about 886 seconds.

The neutron could be said to be merely alive to be part of an atomic nucleus as it ceases to exist after a while if left alone. When it wanders around loose like following its release following decay event or a fission event it may bump into another atomic nucleus and become captured by it. This process is entitle - no surprise - neutron capture. It is finally a nucleon as is a proton both of which make up an atomic nucleus. The neutron is invented of two down quarks and an up quark. When a neutron decays it releases a proton or if you prefer a hydrogen nucleus an electron and an antineutrino.
