properties of a nucleus depend on evenness or oddness of its atomic number (proton number) Z, neutron number N and, consequently, of their sum, the mass...

The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei composed of...

of even/odd Z and N effects well known from experiments. The exact nature and capacity of nuclear shells differs from those of electrons in atomic orbitals...

nuclides are odd-proton / odd-neutron (OO) stable nuclides (see Even and odd atomic nuclei § Odd proton, odd neutron). The five odd–odd bosonic nuclides...

In atomic physics, even–even (EE) nuclei are nuclei with an even number of neutrons and an even number of protons. Even-mass-number nuclei, which comprise...

physics, atomic physics, and nuclear chemistry, the nuclear shell model utilizes the Pauli exclusion principle to model the structure of atomic nuclei in terms...

proton pairs and neutron pairs to occur. An even number of particles is more stable than an odd number due to spin coupling. The mass of an atomic nucleus...

when it has even numbers of both neutrons and protons, but for other cases of odd numbers, the nucleus may have a spin. Normally nuclei with spin are...

is even-numbered but has only one stable isotope. See Even and odd atomic nuclei for more details. Most other metals have greater standard atomic weights:...

having the highest number of isotopes of all elements, ten. See Even and odd atomic nuclei for more details. The half-life found in the experiment was 1...
