Organization of the Periodic Table

Question

Most elements' names end in the suffix -ium. This practice started around the year 1800, with many elements discovered before that having a more common name. However, some elements are more recently discovered and don't end in -ium. Do you notice any patterns for these elements?

Answer 1

The -ium suffix is just a Latin suffix that creates abstract nouns, therefore, it's being used to construct scientific component names from their nomenclature origin, including such minerals (calcium from calx) or person names (gadolinium), and further discussion can be defined as follows:

1. This denotes a metallic element including platinum or barium.
2. It's a group that forms positively charged ions: ammonia chloride, hydronium ion.
3. It indicates a cellular structure, syncytium Etymology, New Latin, via Latin, via Greek -ion, small suffix.
4. Its last found natural element found is francium (87) in 1939.
5. Ever since, plutonium (94), neptunium (93), and astatine (85), which were synthesized inside the lab in 1940, have indeed been discovered throughout nature.
