The Nucleons are bound to each other.
As the distance between two Nucleons reduces, the nuclear force becomes weak between them.
The Nucleons are bound together by a short-ranged attractive
potential called the residual strong force.
Technetium also has numerous nuclear isomers, which are isotopes with one or more excited Nucleons.
The Mass number(A), also known as nucleon number, is the total number of neutrons
and protons in a nucleus.
The radius of a nucleus is approximately equal to 1.07 3√A fm,
where A is the total number of Nucleons.
All the bound protons and neutrons in an atom make up a tiny atomic nucleus,
and are collectively called Nucleons.
