The energy released when an electron is added to a neutral gaseous atom to form an anion is known as electron affinity. [15] Trend-wise, as one progresses from left to right across a period , the electron affinity will increase as the nuclear charge increases and the atomic size decreases resulting in a more potent force of attraction of the ...
Elements are placed in the periodic table according to their electron configurations, [38] the periodic recurrences of which explain the trends in properties across the periodic table. [39] An electron can be thought of as inhabiting an atomic orbital, which characterizes the probability it can be found in any particular region around the atom.
Group 15 consists of the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc). Since 1988, it has been called Group 15 by the IUPAC . Before that, in America it was called Group V A , owing to a text by H. C. Deming and the Sargent-Welch Scientific Company , while in Europe it was called Group V B ...

The melting and boiling points of livermorium are expected to continue the trends down the chalcogens; thus livermorium should melt at a higher temperature than polonium, but boil at a lower temperature. [3] It should also be denser than polonium (α-Lv: 12.9 g/cm 3; α-Po: 9.2 g/cm 3); like polonium it should also form an α and a β allotrope.

About a half hour later, around 9 p.m., “multiple burn victims were reported walking toward a nearby restaurant,” according to the public information officer.
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.
