Ionizationcarbonic acidequilibriumhigh temperaturethermodynamicsThe equilibrium quotients for the first ionization of aqueous carbon dioxide were previously determined at this laboratory. A similar potentiometric technique has now been employed to determine the second ionization quotients in NaCl media to 5m ...
The energy required to remove an electron from the valence shell of the atom of an element is called the ionization energy of the element. The energies for the removal of the successive electrons are called the successive ionization energies like the first, sec...
Rare calcium isotope Ca-48(+) (0.187%) has been selectively loaded in a linear Paul trap using two ultraviolet light emitting diodes with the output power of 85 mW for the second excitation in a two-step photo-ionization process. Isotope selectivity has been achieved by utilizing the isotope...
- 《Journal of Number Theory》 被引量: 78发表: 1996年 Autoionizing States in the Alkali Atoms with Microsecond Lifetimes Discrete atomic energy levels lying between the first and second ionization potentials which are metastable against both auto-ionization and radiative decay have been observed in...
What is the name of the Li element? 1. Why is the ionization energy of helium greater than that of the other elements? Although fluorine is the most electronegative element, silicon tetrafluoride (SiF_4) does not have-a dipole moment. Explain. ...
MALDI-TOF-MS (matrix assisted laser desorption ionization time-of-flight mass spectrometry) was recorded on a Bruker instru- ment (Autoflex II from Bruker Daltonics, Billerica, MA, USA). a-Cyano-4- hydroxycinnamic acid was used for MALDI matrices. Elemental analyses were performed on a Yanaco ...
Final peptide concentration was measured using LavaPep peptide quantification kit and 1 μg of peptides was used for mass spectrometry analysis. Liquid chromatography–mass spectrometry analysis were performed using Ultimate 3000 nano-HPLC system (Dionex) coupled through nanoelectrospray ionization ...
Before use, the purity and stability of lyophilized c-di-GMP were determined by first resuspending the molecule in 0.9% NaCl, creating a 2mm solution; the results were then confirmed by HPLC analysis and electrospray ionization-time-of-flight (mass spectrometry). Cell extract HPLC runs were ...
Electronegativity: The electronegativity of an atom of an element is a measure of the force with which the atom pulls on the shared electrons in a covalent bond. The index is important to investigate the type of bond that exists between atoms of two elements: For ...
