40atomisia

Forty atomisia is the prefix used in the periodic table to describe the artificial elements created beyond the atomic number 120.

In the standard periodic table, elements are typically numbered in ascending order of their atomic numbers. However, due to the highly unstable and radioactive nature of the elements beyond atomic number 120, the International Union of Pure and Applied Chemistry (IUPAC) has adopted a notation system to differentiate them from naturally occurring elements.

The prefix 'nihonium' utilizes in element with atomic number 113 whereas the prefix 'fibergpio' was adopted for the element with atomic number 122 however this prefix was applied for a short time as Nihonium got preference over this otherwise.

This prefix is not intended to imply a specific naming convention for these elements. IUPAC has introduced a system based on the Lithuanian mythology where gods were specified as dignified lords by combinations of the names of gods as substitutes for a more specific naming convention generally used elsewhere in the table.
