A filled shell would have " doubly magic " ( both its proton number of 114 and neutron number of 184 are thought to be magic ).

Could also use some WP : ACCESS updates ( just " pink " is used to denote " odd Neutron number " / " odd N ".

Following electron capture, the atomic number is reduced by one, the neutron number is increased by one, and there is no change in atomic mass.
14.
Chemical properties are primarily determined by proton number, which determines which chemical element the nuclide is a member of; neutron number has only a slight influence.
15.
Atoms with the same atomic number " Z " but different neutron numbers " N ", and hence different atomic masses, are known as isotopes.

Actinides with odd neutron number are generally fissile ( with thermal neutrons ), whereas those with even neutron number are generally not, though they are fissionable with fast neutrons.

Additionally, the neutron count ( neutron number ) may then be derived by subtracting the number of protons ( atomic number ) from the mass number ( nucleon count ).
19.
Neutron numbers for which there are no stable isotones are 19, 21, 35, 39, 45, 61, 89, 115, 123, and 127 or more.
20.
The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7 and 8 respectively.
