Answer:
In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Step-by-step explanation:
Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.
