It forms very few compounds with other elements due to its strong triple covalent bond between the nitrogen atoms. However, given specific conditions, nitrogen can react to form various compounds, such as ammonia (NH3), nitric oxide (NO), and nitrogen dioxide (NO2). These compounds are ...
Bond valence theory has developed slowly over the last 100 years as a method of analyzing and validating the structures of inorganic materials. The various rules of the model have hitherto been strictly empirical, having grown out of the ionic model and the bonding rules proposed by Linus Pauling...
Using the molecular orbital model to describe the bonding in F_2^+, F_2, and F_2^-, predict the bond orders and the relative bond lengths for these three species. How many unpaired electrons are present in each species? How many nonbonding electron pairs, bo...
Answer to: Air is mainly a mixture of nitrogen and oxygen, with small amounts of other gases such as argon and carbon dioxide. What property could...

Answer to: DNA contains all of the following nitrogen-containing bases except: a. adenine. b. uracil. c. guanine. d. cytosine. e. thymine. By...
We found that nitrogen and hydrogen directly react at room temperature and pressures of ~35 GPa forming chains of single-bonded nitrogen atom with the rest of the bonds terminated with hydrogen atoms - as identified by IR absorption, Raman, X-ray diff
(e.g., iron and nitrogen (Fe-N-CDs)), the intrinsic POD activity of CDs was distinctively strengthened, endowing the Fe-N-CDs based immunoassay with superior catalytic activity than HRP [81]. In addition, by virtue of great electron transfer ability, plenty of active sites, and feasible ...
Molecules with a nitrogen-nitrogen (N-N) bond in their structures exhibit various biological activities and other unique properties. A few microbial proteins are recently emerging as dedicated N-N bond forming enzymes in natural product biosynthesis. How
Y is covalent bond, CH 2 , C(O), C═N—R c , C═N—OR c , C═N—SR c , O, S, S(O), S(O 2 ), or NR c ; Z is N or CH; one of U and V is N, and the other is CR c ; and W is O, S, S(O), S(O 2 ), NR c , or NC(O)R c ; in which R ...
