Avogadro's law states that. equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. More exactly, it also includes single atoms, e.g. for a case of noble gases, due the way how IUPAC defines a molecule. But remember the Avogadro law implies ideal gases, similarly as the Gay-Lussac's law, Boyle's law ...Sep 23, 2014 · That is, for core electrons in gold, the electrons are traveling at a significant fraction of the speed of light ( e.g., ~58% for Au 1s electrons). This contracts the Bohr radius of the 1s electrons by ~22%. Source: Wikipedia. This also contracts the size of other orbitals, including the 6s. The absorption you see is a 5d → 6s transition.

Feb 25, 2014 · 39. The inert pair effect describes the preference of late p-block elements (elements of the 3rd to 6th main group, starting from the 4th period but getting really important for elements from the 6th period onward) to form ions whose oxidation state is 2 less than the group valency. So much for the phenomenological part.

Feb 10, 2014 · 5. Hyperconjugation is the interaction between adjacent orbital (empty p p for cation, π π for alkene) with σ σ bond, while common conjugation is between adjacent orbital and π π bond. As one example, one reason why more alkyl substituted alkenes are more stable than less substituted ones is because more alkyl groups provide more ...
