Isotopes are atoms of the same element that contain different numbers of neutrons. For these species, the number of electrons and protons remains constant. This difference in neutron amount affects the atomic mass ( A) but not the atomic number ( Z ). In a chemical laboratory, isotopes of an element appear and react the same.From the nitrogen isotope analysis representing replicate sample analysis and the relationship between the isotopic compositions (δ 15 N-NO 3 −) vs. NO 3-N and (δ 15 N-NH 4 +) vs. NH 4 + in mg/l concentrations Fig. 12a, b of surface and groundwater samples Fig. 12a can be classified into three groups:Natural nitrogen (7N) consists of two stable isotopes: the vast majority (99.6%) of naturally occurring nitrogen is nitrogen-14, with the remainder being nitrogen-15.

Nitrogen-15 tracing technique is very useful and helps to study the nitrogen cycle. Hence the two stable isotopes of Nitrogen are: $^{14}N$ and $^{15}N$ Note: All of these radioisotopes of Nitrogen are short-lived, among which nitrogen-13 (a synthetic isotope) is the longest lived with a half-life of 9.965 minutes. Rest has half-lives below 7. ...Nitrogen-15 (15 N) tracing is a technique to study the nitrogen cycle using the heavier, stable nitrogen isotope 15 N.

The nitrogen stable isotope composition (δ15N) of nitrogen oxides (NO x) is a powerful indicator for source apportionment of atmospheric NO x; however, δ15N-NO x values emitted from ships have not been reported, affecting the accuracy of source partitioning of atmospheric NO x in coastal zones with a lot of ocean vessel activity.Problem #6: Oxygen is composed of three isotopes: One has a a mass of 16.999 amu. This isotope makes up 0.037% of oxygen. Of the other two, one has a mass of 15.995 amu, and the other has a mass of 17.999 amu. Calculate the abundance of the other two isotopes, using the average atomic mass of 15.9994 amu. Solution:Nitrogen-15 (15N) tracing is a technique to study the nitrogen cycle using the heavier, stable nitrogen isotope 15 N. Despite the different weights, 15 N is involved in the same chemical reactions as the more abundant 14 N and is therefore used to trace and quantify conversions of one nitrogen compound to another. 15 N tracing is applied in ...
