How many binary borane hydrides are known? | <text>How many binary borane hydrides are known?</text><reasoning>Although hydrides can be formed with almost all main-group elements, the number and combination of possible compounds varies widely; for example, there are over 100 binary borane hydrides known, but only one binary aluminium hydride. Binary indium hydrid... |
What kind of movement does the electron not have in ground state? | <text>What kind of movement does the electron not have in ground state?</text><reasoning>A more accurate description of the hydrogen atom comes from a purely quantum mechanical treatment that uses the Schrödinger equation, Dirac equation or even the Feynman path integral formulation to calculate the probability density... |
What model id used to calculate energy levels of hydrogen? | <text>What model id used to calculate energy levels of hydrogen?</text><reasoning>The energy levels of hydrogen can be calculated fairly accurately using the Bohr model of the atom, which conceptualizes the electron as "orbiting" the proton in analogy to the Earth's orbit of the Sun. However, the electromagnetic force ... |
