A neutron's outer shell is negative and its core is positive. It peacefully hides a constant fight between them. It's a symbol of self-control and inner wisdom. Until it beta decays and beats the crap...
Neutrons don’t have an „outer shell“. They are made of three quarks held together by strong nuclear forces that have a quantum-electrostatic nature. Also, neutrons don’t beta decay, the nucleus does, which emits an electron or positron depending on the emission type.
