even-odd nucleus comparison table

Subject	is part of	is a kind of	has quantum behavior	has spin	obey	has definition	has charge	is accelerated by
fermion		particle	Fermi-Dirac statistics	half-integral	exclusion principle	Elementary particle with fractional spin. The proton, electron, neutron, and other elementary particles are all fermions.
nucleus	element	charged particle			uncertainty principle	The massive, positively charged central part of an atom, composed mainly of protons and neutrons, around which the electrons revolve. The radius of an atomic nucleus is directly proportional to the cube root of its mass. Density at least 1014 g cm-3. Radius 10-12-10-13 cm.	non-zero	electric or magnetic fields
even-odd nucleus	element	fermion	Fermi-Dirac statistics	half-integral	exclusion principle	Nucleus that contain even numbers of protons but odd numbers of neutrons.	non-zero	electric or magnetic fields
