Nomenclature of Elements with Atomic Number above 100

According to the present periodic chart, 118 elements are now known to humanity, of which 24 are synthesized, and the remaining 117 are found in nature. Some of these elements have been known for a long time. In contrast, others have just recently been discovered by a team led by Glen Seaborg at the Lawrence Berkeley National Laboratory in Berkeley, California. 

Many of these aspects have been given names and symbols, although these symbols and names are not always utilised in the same way across different cultures. 

  • Some of them have two names or symbols assigned to them. For example, Both American and Soviet scientists have claimed to have discovered an element with the atomic number Z = 104. 
  • The Americans designated it as Rutherfordium (Rf), but the Soviets established it as Kurchatovium (K) (Ku). 
  • In the same manner, another element with an atomic number equal to 107, known as Neilsbohrium (Ns), as well as the element Bohrium (Bo), have been discovered (Bh). 

A committee on the nomenclature of inorganic chemistry (CNIC) was established by the International Union of Pure and Applied Chemistry (IUPAC) to assign a transparent system of nomenclature for elements with Z> 100. (also known as superheavy elements). 

After extensive consultation with experts throughout the globe, the International Union of Pure and Applied Chemistry (IUPAC) settled on the official names for elements with atomic numbers 104 to 110 in 1997. It proposed a method for the naming of these elements.

The following are the most significant aspects of IUPAC Names of elements with atomic numbers more than 100:

  1. The names may be derived directly from atomic numbers by writing the numerical roots of the needed number from 0-9 and then adding the suffix ‘ium’ to the end of the number. It is necessary to utilise a combination of Latin and Greek origins to avoid duplication in the sign. The roots for the numbers 0-9 are displayed in the table that follows:

The origins of the International Union of Pure and Applied Chemistry (IUPAC) nomenclature of elements.

  1. Occasionally, names are omitted altogether. In the case of biium, it is possible to write bium.
  2. To get the symbol for an element, write down the roots of all the integers in that element’s atomic number and then add the suffix “ium” to it.

As an example, consider:

The element’s name is generally given to the person who discovered it, frequently the same person. Various sources have inspired artists throughout history, including historical figures, geographical places, natural or chemical qualities, and, more recently, the names of prominent scientists. 

The International Union of Pure and Applied Chemistry must approve it (IUPAC) to execute the idea.

A provisional designation is necessary until the International Union of Pure and Applied Chemistry (IUPAC) has given a permanent name and symbol to the superheavy elements recently found or yet to be discovered.

In 1978, the Commission on the Nomenclature of Inorganic Chemistry of the International Union of Pure and Applied Chemistry settled on a systematic naming scheme for elements with atomic numbers more than 100, including those that have yet to be discovered. 

Following the standards outlined by the Commission, the names of these components should be arranged in a logical sequence. This method is still in use today.

  1. Element names are derived directly from the element’s atomic number, which appears as the Latin number after the name.
  2. To name the element, the roots are organised according to the atomic number. The letter ‘ium’ is added at the end. “enn” is removed when the final ‘n’ comes before the word “nil,” and when the last ‘I’ appears before the word ‘ium’, “enn” and “tri” are omitted when the final ‘n’ seems before these words.
  3. The initial letters of the number roots that make up the element’s name symbolise the symbol.
  4. When pronouncing “un,” it must speak the word “moon” to execute the idea with a long “u.” Each root should be pronounced separately from the other root in the element names (s).

For all Z > 100 elements, the International Union of Pure and Applied Chemistry (IUPAC) nomenclature has been proposed. These elements’ names are derived from the nuclear number’s numeric origins. If an element’s atomic number is more than 100, the IUPAC ordered Latin numerals to be used instead.

Fermium is a manufactured chemical element. The atomic number is 100, and the chemical symbol is Fm. If you’re looking for an actinide and the heaviest part formed by neutron bombardment of lesser features, fermium is the last one you’ll be able to get your hands on in large quantities.

The twelve natural elements are earth, water, wind, fire, thunder, ice, force, time, flower, shadow, light, and the moon. Earth, water, wind, fire, thunder, ice, force, time, flower, shadow, light, and the moon are all-natural elements.


Uranium, the most massive naturally occurring element, contains 92 protons, 30 places below the hypothetical new element in the periodic table. In the laboratory, scientists have created elements up to and including 118, although they are all very unstable.

After earth, air, fire, and water, aether is the fifth element, also known as the aether. Initially, the scientific community considered space the fifth element since it was difficult for people to comprehend that the stars and everything else in space was other elements.

Ancient and mediaeval physics refers to it as the fifth element, and it is also known as the quintessence, ethereum, or the fifth substance of the universe (the fifth element).
