Summary
Scientists explore superheavy elements (SHEs), synthesized via nuclear reactions, to understand matter
Area of Science:
- Nuclear Physics and Chemistry
- Exploration of extreme limits of matter
Background:
- Superheavy elements (SHEs) are synthesized atom-at-a-time in heavy-ion nuclear reactions.
- Known SHEs up to element 118 are short-lived and located in the seventh period, extending the transactinide series.
- Their chemical properties are often unexpected due to relativistic effects.
Purpose of the Study:
- Investigate the extreme limits of matter and nuclear shell stabilization.
- Explore the chemical properties of SHEs, particularly elements like copernicium (112) and flerovium (114).
- Understand the influence of relativistic effects on atomic electrons and chemical behavior.
Main Methods:
- Synthesis of SHEs through heavy ion induced nuclear reactions.
- Experimental and theoretical studies of SHE chemical properties.
- Application of fully relativistic quantum chemical models.
Main Results:
- SHEs exhibit unique chemical properties influenced by relativistic and electron-shell effects.
- The metallic or noble gas-like character of SHEs is under investigation.
- Modern quantum chemical models are challenged by SHE properties.
Conclusions:
- SHEs offer insights into relativistic effects on atomic structure and chemical properties.
- They serve as a test bench for advanced quantum chemical models.
- Understanding SHEs pushes the boundaries of the periodic table and matter.

02:31Elements: Chemical Symbols and Isotopes
134.6K
A chemical symbol is an abbreviation used to indicate an element or an atom of an element. For example, the symbol for mercury is Hg. The same symbol is used to indicate one atom of mercury (microscopic domain) or to label a container of many atoms of the element mercury (macroscopic domain).
Some symbols are derived from the common English name of the element; others are abbreviations of the name in another language — Latin, Greek or German. For example, the symbol for aluminum (common...

A chemical symbol is an abbreviation that is used to indicate an element or an atom of an element. For example, the symbol for mercury is Hg. We use the same symbol to indicate one atom of mercury (microscopic domain) or to label a container of many atoms of the element mercury (macroscopic domain).
Some symbols are derived from the common name of the element; others are abbreviations of the name in another language. Most symbols have one or two letters, but three-letter symbols have been used...

03:25The Periodic Table
140.6K
As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...

21.1K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

04:00Periodic Classification of the Elements
67.8K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

03:26Electron Configuration of Multielectron Atoms
68.7K
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...
