#### The Math / Science

The neutron is a subatomic hadron particle that has the symbol n or n^0. Neutrons have no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen-1, the nucleus of every atom consists of at least one neutron as well as one or more protons.  This constant is specified with a standard uncertainty (standard deviation) of: 0.000 000 074 E-27 kg
