It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope O-17 (Oxygen, atomic number Z = 8, mass number A = 17). Landolt-Brnstein Homepage Introduction Index...
While the number of protons remains the same for all isotopes, otherwise the atom would change elements to one with a matching number of protons, the neutrons in the nucleus can change without changing the element. However, changing numbers of neutrons will result in isotopes of differing masses...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
The charge number (z) is the total charge on an ion divided by the elementary charge (e), 1.602177 × 10− 19 C. The thomson is defined as 1 Th = 1 u/e = 1.036426 × 10− 8 kg C− 1. The mass of a (poly)peptide in proteomics is described by its monoisotopic mass, ...
In an ocean that is rapidly warming and losing oxygen, accurate forecasting of species’ responses must consider how this environmental change affects fundamental aspects of their physiology. Here, we develop an absolute metabolic index (ΦA) that quanti
Therefore, from all of the recent examples of modeling and observations of circumstellar disks a number of mechanisms can be considered that might contribute to very early heating and depletion of moderately volatile elements at 1 AU. However, some of these are localized processes and the timescale...

Unfortunately, similar but geographically distinct fluvial and lacustrine records do not yet exist for the late Frasnian, hindering efforts to further support the assertion that events at Heintzbjerg were indicative of global trends. However, there are a number of marine records which overlap and incl...
An algorithm for filtering molecular formulas is derived from seven heuristic rules: (1) restrictions for the number of elements, (2) LEWIS and SENIOR chemical rules, (3) isotopic patterns, (4) hydrogen/carbon ratios, (5) element ratio of nitrogen, oxygen, phosphor, and sulphur versus carbon...
