The Nitrogen Elements: Nitrogen, Phosphorous, Arsenic, Antimony, Bismuth (Understanding the Elements of the Periodic Table) by Greg Roza



Understanding the Elements of the Periodic Table. The nitrogen elements consist of Phosphorous, Arsenic, Antimony, and Bismuth. This book explains their properties, uses, history, and chemical makeup.

Occurrence and Recovery of the Elements Antimony Antimony is found in nature in a number of minerals including stibnite (Sb 2 S 3 ) ullmanite (NiSbS). Small amounts of native antimony have been found. Sb 2 S 3 + 3Fe 2Sb + 3FeS In antehr process, some ores can be heated to evolve the oxide Sb 2 O 3 and this in turn can be reduced by charcoal in the presence of sodium sulphate, to ensure mixing, to form elemental antimony

All are important elements Increasing trend to metallic character and cationic behavior from top to botom in the grroup Nitrogen is different with the other elements, even phosphorus Slideshow. Occurrence and Recovery of the Elements. Antimony is found in nature in a number of minerals including. Some ores are treatable under reducing conditions to form Sb2S3. Sb2S3 + 3Fe 2Sb + 3FeS.

Elemental Phosphorus White Phosphorus Black Phosphorus White Phosphorus: Reaction on previous slide Ignites spontaneously in air Stored under water Red Phosphorus: Heat white phosphorus at 300 C in inert atm for several days Does not ignite in air Structure: contain linear chain Black Phosphorus The most stable form Formed when P heated under high pressure. The arsenic is condensed out as a solid. FeAsS (700C) FeS + As(g) + As(s). Slide 7. Occurrence and Recovery of the Elements Antimony Antimony is found in nature in a number of minerals including stibnite (Sb 2 S 3 ) ullmanite (NiSbS).

Nitrogen group element: The six elements-nitrogen, phosphorus, arsenic, antimony, bismuth, and moscovium-of Group 15 of the periodic table. Similarities in orbital arrangement. In the periodic table, each of the nitrogen group elements occupies the fifth position among the main group elements of its period, a position designated 15. In terms of the electronic configuration of its atoms, each nitrogen group element possesses an outermost shell of five electrons.

Nitrogen family The group 15 elements of periodic table are known as Nitrogen family. Here the members are Nitrogen, Phosphorus, Arsenic, Antimony & Bismuth. Symbols for group 15 elements Nitrogen N Phosphorus P Arsenic As Antimony Sb Bismuth Bi. The group 15 elements have outer electronic configurations ns2np3 with no partly filled inner levels. The atomic number of nitrogen is 7. For living organisms this is an essential element. Nitrogen is a major constituent of proteins & nucleic acids. Nitrogen-14 & Nitrogen-15 are considered as the 2 major isotopes of nitrogen

4 Exceptions in the group  Nitrogen is not a solid at room temperature Are they metal, nonmetals, or metalloids?  Nitrogen and Phosphorous are non metals, Arsenic and Antimony are metalloids and Bismuth is a metal. 5 What state do they exist in at room temp?  They are solids except for Nitrogen which is a gas. 6 Trends and valence electrons They get more dense as the list goes down They get more dense as the list goes down 5 . - 5 . -  .

This allows a better understanding of the physical nature of the interaction. Multiple-bonded compounds of the heavier group 15 elements phosphorus, arsenic, antimony, and bismuth represent an important group of materials. This chapter presents key developments in this field from 2000 to 2010, focusing largely on doubly and triply bonded compounds having coordination numbers 1 and 2. In particular, developments in the synthesis, reactivity, and use in functional materials.

General s of Various Elements/Group 15. < General Chemistry‎ Chemistries of Various Elements. Group 15 (VA) contains nitrogen, phosphorous, arsenic, antimony, and bismuth. Elements in Group 15 have five valence electrons. Because the elements can either gain three electrons or lose five to gain a stable configuration, they more often form covalent compounds unless bonded to an active metal.

Readers learn all about the nitrogen elements; nitrogen, phosphorus, arsenic, antimony and bismuth, what they are, their properties and more. Includes colorful diagrams and photographs, table of contents, sidebars, the periodic table of elements, glossary, research sources, bibliography, index and author profile. 5 chapters, 48 pages.
