WebAtomic Size Definition. Atomic size is the mean distance between the nucleus and the outermost valence shell electron of an atom. It is measured by picometer (pm) units which is equal to 10^ {-12} 10−12 meter. WebAn atom with an unstable nucleus, called a radionuclide, is characterized by excess energy available either for a newly created radiation particle within the nucleus or via internal conversion. During this process, the radionuclide is said to undergo radioactive decay. portland investment group companies house
