The neutron is a subatomic hadron particle which has the symbol n or n0
, no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. Neutrons are necessary within an atomic nucleus as they bind with protons via the strong force; protons are unable to bind with each other due to their mutual electromagnetic repulsion being stronger than the attraction of the strong force. The number of neutrons is the neutron number and determines the isotope of an element. For example, the abundant carbon-12 isotope has 6 protons and 6 neutrons, while the very rare radioactive carbon-14 isotope has 6 protons and 8 neutrons.
While bound neutrons in stable nuclei are stable, free neutrons are unstable; they undergo beta decay with a mean lifetime of just under 15 minutes (881.5±1.5 s). Free neutrons are produced in nuclear fission and fusion. Dedicated neutron sources like research reactors and spallation sources produce free neutrons for use in irradiation and in neutron scattering experiments. Even though it is not a chemical element, the free neutron is sometimes included in tables of nuclides. It is then considered to have an atomic number of zero and a mass number of one, and is sometimes referred to as neutronium.[citation needed]

Plot: Film adaptation of street tough Jim Carroll's epistle about his kaleidoscopic free fall into the harrowing world of drug addiction. As a member of a seemingly unbeatable high school basketball squad, Jim's life centers around the basketball court and the court becomes a metaphor for the world in his mind. A best friend who is dying of leukemia, a coach ("Swifty") who takes unacceptable liberties with the boys on his team, teenage sexual angst, and an unhealthy appetite for heroin -- all of these begin to encroach on young Jim's dream of becoming a basketball star. Soon, the dark streets of New York become a refuge from his mother's mounting concern for her son. He can't go home and his only escape from the reality of the streets is heroin for which he steals, robs and prostitutes himself. Only with the help of Reggie, an older neighborhood friend with whom Jim "picked up a game" now and then, is he able to begin the long journey back to sanity.
