The pnictogens [1] (/ ˈ p n ɪ k t ə dʒ ə n / or / ˈ n ɪ k t ə dʒ ə n /; from Ancient Greek πνῑ́γω (pnígo) ' to choke ' and -gen ' generator ') are the chemical elements in group 15 of the periodic table. This group is also known as the nitrogen group or nitrogen family. Group 15 consists of the elements nitrogen (N ...

2023年6月30日 · All Group 15 elements tend to follow the general periodic trends: Electronegativity (the atom's ability to attract electrons) decreases down the group. Ionization energy (the amount of energy required to remove an electron from the atom in its gas phase) decreases down the group. Atomic radii increase in size down the group.

Group 15 elements of the periodic table constitute the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb) and bismuth (Bi). These elements are put together called p-block elements.

Like the group 14 elements, the lightest member of group 15, nitrogen, is found in nature as the free element, and the heaviest elements have been known for centuries because they are easily isolated from their ores. Antimony (Sb) was probably the first of the pnicogens to be obtained in elemental form and recognized as an element.

Group 15 elements (also known as pnictogens) consist of nitrogen, phosphorus, arsenic, antimony, bismuth, and moscovium. Group 15 elements have similar electron configurations, with each element having five valence electrons. When descending group 15, the elements change from nonmetals to metalloids and then to metals.

2019年5月7日 · The nitrogen family is element group 15 of the periodic table. Nitrogen family elements share a similar electron configuration pattern and follow predictable trends in their chemical properties.

2023年6月30日 · The pnictogen group, or nitrogen group, is located in column 15 of the periodic table. This family consists of the elements nitrogen, phosphorus, arsenic, antimony, bismuth, and ununpentium (N, P, As,…

2025年1月28日 · In this article, we will study all about the chemical properties and uses of a group in the \({\rm{p}}\)-block that is group \(15\)- Nitrogen family. Group 15 Elements The \({\rm{p}}\)-block elements are placed on the right-hand side of the periodic table from group \(13\) to \(18.\)

Group 15 elements include nitrogen, phosphorus, arsenic, antimony and bismuth. Nitrogen is the real constituent of the air and records for 78% of it by volume. It is the primary member of this group and happens in a free state as a diatomic gas, N 2. Phosphorus is a fundamental constituent of animal and plant matter.

In group 15, nitrogen and phosphorus behave chemically like nonmetals, arsenic and antimony behave like semimetals, and bismuth behaves like a metal. Nitrogen forms compounds in nine different oxidation states. The stability of the +5 oxidation state decreases from phosphorus to bismuth because of the inert-pair effect.
