Here we are not going to talk about the detail of different correction theory, straightly come to the conclusion of quantum mechanics. Schrödinger Equation of Hydrogen-Like Atoms Any atom comprising a single electron orbiting a nucleus of charge \mathrm{Z} can be described as hydrogen-like....
Unhappily the "mode of combination" of atoms within a compound was no more an experimentally accessible molecular parameter in the first two decades of the nineteenth century than it had been in the seventeenth and eighteenth centuries, and this kind of explanation, like the earlier reductionism of...
Element atomicnumber 1is themost abundant elementin the universe. In terms of a sheer number of atoms, about 90% of atoms in the universe are hydrogen. Because the element is so light, this translates into around 74% of the universe by mass. ...
Considering the introduction of pulsed electric current, hydride configuration in pure titanium is thermodynamically unstable, and the electromigration effect in kinetics also accelerates desorption of hydrogen atoms. The evolution of hydride configuration and desorption of hydrogen atoms are beneficial to the...
