Electron and phonon calculations are presented for the ternary CaTaN 2 of trigonal 伪 - NaFeO 2 -structure. Both density functional theory and the empirical tight-binding method are employed to yield a realistic description of electronic and vibrational properties, and also reasonable estimates of ...

In 1913, the Danish scientist Niels Bohr suggested a reason why the hydrogen atom spectrum looked this way. He suggested that the electron in a hydrogen atom could not have any random energy, havingonlycertain fixed values of energy that were indexed by the numbern(the samenin the equati...

In this paper our recent studies of organic salts are reviewed including new results. We analysed an electronic structure and superconductivity of layered organic materials on the basis of bis(ethylenedithio)tetrathiafulvalene molecule (BEDT-TTF, hereaft
These electrons are the electrons that reside in the outermost orbital. They are mostly responsible for any chemical reaction that happens between two molecules.Answer and Explanation: The number of valence electrons in the molecule is equal to the sum of valence electrons of each atom present in...
Protons and neutrons are within the atom's nucleus while the electrons surround it. The distribution of the electrons around the nucleus can be represented by the atom's electron configuration written in the form nle, where n is the energy level or distance from the nucleus, l is the ...
- Penultimate Shell (n=2): 2s² + 2p⁶ = 8 electrons- Conclusion: Both shells have 8 electrons. This is the correct species. Final AnswerThe species that has the same number of electrons in its outermost and penultimate shell is Ca²⁺. --- Show More ...

The complete system is susceptible to illumination at 532 nm, as shown by the CV in Fig.S17. Illumination of the entire system at plasmon resonance led to a slight decrease in offset potential (ca. 0.05 V) but, more importantly, an increase in the catalytic wave photocurrent. ...
