The approximate boiling points for hydrogen compounds of some elements in the nitrogen family are (SbH3 15°C), (AsH3 -62°C), (PH3 —87°C), and (NH3 —33°C). The best explanation for the fact that NH3 does not follow the trend of the other hydrogen compounds is... 

Bismuth is the fifth member of the nitrogen family of elements and, like its congeners, possesses five electrons in its outermost shell, 6s 6p. In many compounds, the bismuth atom utilizes only the three 6p electrons in bond formation and retains the two 6x electrons as an inert pair. Compounds are also known where bismuth is bonded to four, five, or six other atoms. Many bismuth compounds do not have simple molecular structures and exist in the solid state as polymeric chains or sheets. 

It will pay you to know (without having to look in the periodic table or tables of electron configurations) that the halogens (F, Cl, Br, I, At) all have seven valence electrons, that the oxygen family (O, S, Se, Te) all have six, that the nitrogen family (N, P, As) have five, that the carbon family (C, Si) have four, and that the boron family (B) have three It will also pay you to know that electronegativities decrease from right to left in a row, or from top to bottom in a column, in the periodic table... 

Atmospheric nitrogen species—both characterized and uncharacterized—include nearly all oxidation states of nitrogen and encompass a large number of distinct molecules. With the crucial roles these species play, the low concentrations of interest, the wide dynamic range of concentrations encountered, and the wide variety of species included in this family, analytical chemists face many challenges in the development of instrumentation for characterizing the atmospheric nitrogen family. 

Development of Techniques for Currently Unmeasured Species in the Troposphere. There is evidence that there are additional members of the nitrogen family that have not been measured. With the possible exceptions of HN03 and particulate N03, reasonably reliable techniques are currently available for in situ measurement of the concentrations of the major contributors to the NOy family in the rural troposphere. In addition, a measurement of the total family concentration is available. Therefore the total of the concentrations of the individually measured species can be compared with the measured family concentration. This comparison can then... 

Phosphorus is one of the best soft donor atoms for Cu thus many Cu -phosphine complexes have been reported, including ones with other hgands that by themselves would be unlikely to sufficiently stabihze Cu. By far, most of the known complexes involve monodentate phosphine ligands. As one goes down the nitrogen family, progressively fewer complexes have been characterized, such that substantially less arsine-coordinated complexes have been reported and there are only a handful of stibine species. 

Nitrogen is the first member in Group 15 (VA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Nitrogen is in a family group named after itself Other elements in the nitrogen family are phosphorus, arsenic, antimony, and bismuth.

The structure has a total of 32 electrons of these, 21 are accounted for by the chlorines (3 Cl s x 7 valence electrons each) of the 11 electrons remaining, 6 come from the oxygen. This leaves 5 electrons unaccounted for these must come from E. Therefore, E must be a member of the nitrogen family and since it is a third period element E must be phosphorous(P)... 

Bismuth, Bi, the 83rd element of the periodic table is the most metallic and the least abundant of the elements in the nitrogen family (group 15). It has an atomic mass of 208.980 and a ground state electronic configuration of [Xe] 4f 5d %s 6p. The bismuth atom usually utilizes the three 6p electrons in bond formation and retains the two 6s electrons as an inert pair, hence the oxidation state -1-3 exhibited by bismuth in the vast majority of its compounds. However, a variety of organobismuth compounds can contain the element in the -1-5 oxidation state. Coordination numbers are 2, 3,4, 5 and 6. Bismuth not only has metallic characteristics but also exhibits many properties similar to those of semiconductors and insulators. Consequently, it is often classified as a semi-metal or metalloid. Bismuth compounds are usually colorless unless the metal is bound to a chromophore. 

The uniqueness of bismuth is most characterized by its low toxic nature in spite of its heavy metal status in the nitrogen family, since it is a general trend of elements that the toxicity increases as you go down a group. Hence traditionally, it has been used widely in medicine and veterinary practice. Closely related arsenic and antimony compounds are generally highly toxic. LD50 (mg/ kg) values of bismuth oxychloride (BiOCl) and bismuth oxide are reported to be 22 000 (rat, oral) and 10 000 (mouse, oral), respectively. Accidental... 

The odd nitrogen family (NOy) is defined as the sum of all nitrogen-containing species except the major atmospheric constituent N2 and the source gases such as nitrous oxide (N20), hydrogen cyanide (HCN) and methyl cyanide (CH3CN). Thus, in the middle atmosphere, if we include... 

Antimony [7440-36-0] is the fourth member of the nitrogen family and has a valence shell configuration of Ss 5p[ The utilization of these orbitals and, in some cases, of one or two 5 6 orbitals permits the existence of compounds in which the antimony atom forms three, four, five, or six covalent bonds.
