How does the structure of the atom determine its usefulness in nuclear science?

Answer 1

There is nothing in the structure of an atom that could show its usefulness in nuclear science. A useful isotope is thallium-201. This decays by electron capture to mercury-201. It is useful because it decays by electron capture and not positron emisson. This makes it useful for nuclear heart stress tests. It does not emit ionizing radiation. There is nothing in the atomic structure that could predict this behavior. Another useful isotope is technetium-99m. This is element number 43. There is nothing in its structure that could predict that it has no stable isotopes.

Answer 2

Atoms with mor nutrions explode when broken bigger than normal atoms. Though most atoms like that are not that unstable. So you need to bix a stable atom with an unstable atom to make it explode. If the atom did not work like this we would not have some of the nuclear bombs we have today.
