Nitrogen group antimony

Arsenic is a group 15 element on the periodic table along with nitrogen, phosphorus, antimony, and bismuth. The atomic mass of arsenic is 74.921 60 atomic mass units (amu) and its atomic number (Z)... 

Phosphorus is found in Group 15 (VA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Phosphorus is part of the nitrogen family along with nitrogen, arsenic, antimony, and bismuth. 

Phosphorus is a nonmetallic chemical element which, together with nitrogen, arsenic, antimony, and bismuth, comprise Group VA of the Periodic Table of the elements. Phosphorus has an atomic weight of 30.9738, and in all naturally occurring compounds is present as the stable isotope, P. Radioactive P has a half-life of... 

Phosphoras belongs to Group VB in the periodic table along with nitrogen, arsenic, antimony, and bismuth. It exhibits -I-3 and -I-5 valence states. Therefore, in most cases it forms tri- and pentavalent salts. It occurs widely in nature and many of its compounds find wide commercial applications. Phosphorus compounds that are hazardous may be classified under a few broad categories ...

Nitrogen is unusual in forming so many oxides. The acidity of the Group V oxides falls from phosphorus, whose oxides are acidic, through arsenic and antimony whose oxides are amphoteric, to the basic oxide ofbismuth. This change is in accordance with the change from the non-metallic element, phosphorus, to the essentially metallic element, bismuth. The +5 oxides are found, in each case, to be more acidic than the corresponding + 3 oxides. 

Nitrogen is a colorless diatomic gas. Phosphorus has several elemental forms, but the most common is a red solid that is used for match tips. Arsenic and antimony are gray solids, and bismuth is a silvery solid. Classify these elements of Group 15 as metals, nonmetals, or metalloids. 

We see that Group 15 passes through all three classes of elements. The elements with the lowest Z values, nitrogen and phosphoms, are nonmetals. The element with highest Z value, bismuth, is a metal, and the two elements with intermediate Z values, arsenic and antimony, are metalloids. 

Bismuth has the largest atom of any element of Group V, and it holds its electrons less tightly than the others do. It is a metal, but not a very good one. It is brittle and is also a poor conductor of electricity. Antimony and arsenic are semi-metals. Phosphorus and nitrogen are not metallic at all. Nitrogen exists in nature as a gas. 

Not all elements in these groups have the same properties and characteristics. For instance, in group 15, nitrogen is a gas, whereas the element just below it in group 15 is phosphorous, anon-metallic solid (semimetal). Just below phosphorous is arsenic (semimetal), followed by antimony and then bismuth, which are more metal-like. These last two, antimony and bismuth, are metals that might be considered an extension of periods 5 and 6 of the transition elements. 

Since N-nitrosoimmonium ions seem to be involved in the hydrolysis of a-acetates, it should be possible to isolate such species as stable salts. For this purpose, we selected a system such as XVII in which the phenyl group should provide further stabilization of such a carbonium ion. After the reaction of nitrosyl chloride with the corresponding imines, addition of antimony pentachloride resulted in the precipitation of pale yellow solids these could be isolated and stored under nitrogen for several days at room temperature. ...
