Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, or superheavies for short, are the chemical elements with atomic number greater than 104. [1] The superheavy elements are those beyond the actinides in the periodic table; the last actinide is lawrencium (atomic number 103).

In chemistry, transactinide elements (also, transactinides, or super-heavy elements) are the chemical elements with atomic numbers from 104 to 120. Their atomic numbers are immediately greater than those of the actinides, the heaviest of which is lawrencium (atomic number 103).

Transactinide elements are elements that have atomic numbers greater than the actinides. They have atomic numbers from 104 to 120. They are all synthetic and radioactive. They range from 104 rutherfordium to 118 oganesson on the periodic table.

2024年9月20日 · In chemistry, transactinide elements (also, transactinides, or superheavy elements) are the chemical elements with atomic numbers from 104 to 120. Their atomic numbers are immediately greater than those of the actinides, the heaviest of …

The term "transactinides" is used to refer to all elements beyond the actinides—that is, those elements with atomic numbers larger than 103. Lawrencium, with atomic number 103 and a full inner 5f electron shell, ends the actinide series.

A contemporary and definitive compilation of chemical properties of all of the actinide elements; Features technologically important elements uranium and plutonium, as well as the transactinide elements

2025年2月9日 · Elements with an atomic number greater than 103, i.e. elements above lawrencium in the periodic table. So far, elements up to 116 have been detected. Because of the highly radioactive and transient nature of these elements, there has been much dispute about priority of discovery and, consequently, naming of the elements.

This article gives a brief summary of the reported syntheses and nuclear properties of the transactinide elements as well as chemical investigation of those elements.

2006年1月1日 · This chapter gives a brief summary of the reported discoveries, confirmation, and nuclear properties of the claimed and confirmed transactinide elements through the year 2004.

In chemistry, transactinide elements are the chemical elements with atomic numbers greater than those of the actinides, the heaviest of which is lawrencium (103). The transactinide elements are also called super-heavy elements .
