isotoopittomien
Isotoopittomien refers to elements that naturally occur as a single stable isotope. These elements have an atomic mass number that is unique for all atoms of that element found in nature. This means that unlike most elements which are a mixture of various isotopes, some with different numbers of neutrons, isotoopittomien elements consist of only one type of atom in terms of neutron count.
The occurrence of isotoopittomien elements is a consequence of nuclear stability and the processes of nucleosynthesis.
When studying the atomic weight of these elements, one can use the mass number of their single
