Периодическая таблица ионов и изотопов

The periodic table consists of 118 known elements, and everything in the universe—whether living or non-living—is composed of one or more of their atoms. At first glance, the table may appear small and even simple to students. However, within every atom lies an astonishing world of possibilities, expressed through the vast range of ions and isotopes that each element can form. When viewed from this deeper perspective, the periodic table is no longer a list of 118 entities—it multiplies into hundreds, even thousands, of unique chemical species. Each element can exist in multiple oxidation states, combine with other elements in countless ways, and occur in several isotopic forms, both stable and radioactive.
