Numbers unique

Which property—the atomic mass or atomic number—uniquely identifies a chemical element Explain how the property uniquely identifies each atom. 

However evaluation of safety in animal models of disease may be difficult to conduct with strict adhere to current good laboratory practices (cGLPs) due to novel routes of administration, limited animal numbers, uniqueness of the animal model of disease, and/or novel surgical procedures. In such cases the principles of the regulation can still be followed, and where deviations occur, they should be evaluated for their impact on the expected clinical application and discussed. An in-depth discussion should be provided to support a regulatory submission. 

UNS. Unified Numbering System satisfies the need for a common designation system for all alloys. The UNS number uniquely identifies the chemical composition of alloys that have been fixed by other organizations, such as one of the metal manufacturers associations. If the alloy is proprietary or produced by a limited number of suppliers, the chemical composition is established by the supplier. The... 

Another comprehensive organic nomendature was proposed by Terent ev ti ol [30]. Ring systems are numbered uniquely by picking a path, and acyclic compounds are numbered and named uniquely as sums of unbranched components. The name of the first example in Figure 10 is similar to a von Baeyer name. The numerical data are read as follows.

Figure 19. Plot of cumulative fraction of low energy conformers for isolated met-enkephalin, which is equal to the number of unique conformers within the first 8, 12, and 16 energy bins over the total number unique conformers, versus temperature. Both EDA and FEDA data are plotted.

In an ideal gas, the state of the system can be described microscopically at any instant in time if we know the positions and momenta of all of the particles. Treating every particle as a numbered unique particle would give us the microstate. Each particle being identical, however, and therefore interchangeable, means that there will be a very large number of microstates for each macrostate.
