The Periodic Table and Organismal Elements

161.7K
OverviewElements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally-occurring, and fewer still are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.The Periodic Table Provides Information...

Elements: Chemical Symbols and Isotopes

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...

The Periodic Table

115.4K
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,...

Periodic Classification of the Elements

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...

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...

Area of Science:

  • Nuclear Chemistry
  • Atomic Physics
  • Periodic Table Trends

Background:

  • Heaviest elements like seaborgium, bohrium, and hassium chemically characterize according to periodic table groups.
  • Relativistic effects can significantly alter chemical properties of superheavy elements.
  • Previous studies suggested element 112 might deviate from group 12 trends due to its electronic structure.

Purpose of the Study:

  • To reliably chemically characterize superheavy element 112.
  • To investigate the adsorption properties of element 112 on a gold surface.
  • To determine if element 112 exhibits typical group 12 chemical behavior.

Main Methods:

  • Production of two atoms of (283)112 via alpha decay of (287)114, formed from 48Ca + 242Pu fusion.
  • Adsorption of produced (283)112 atoms onto a gold surface.
  • Comparative analysis of adsorption characteristics with mercury and radon.

Main Results:

  • Element 112 demonstrated high volatility, similar to but distinct from radon.
  • Element 112 exhibited metallic interaction with the gold surface.
  • Adsorption properties confirmed element 112 as a typical member of group 12.

Conclusions:

  • Element 112 is a volatile metal, behaving as expected within group 12.
  • The successful production and characterization validate 48Ca-induced fusion reactions for accessing superheavy elements.
  • This work supports the ongoing search for the 'island of stability' for superheavy elements.
