I have a doubt here, if electron absorbs energy from the outside source and jumps to the higher energy state, it will be now storing absorbed energy, as potential energy at the excited state. If electron emits all the absorbed energy (quanta-difference in energies betw...
Even an atom is mostly empty space.If the proton of a hydrogen atom was the size of the sun on this map, we would need 11 more of these maps to show the average distance to the electron.Some theories say all this emptiness is actually full of energy or dark matter and that nothing ...
aThe reducing properties are generally associated with the presence of reductones, which have been shown to exert antioxidant action by breaking the free radical chain via donating a hydrogen atom. 减少的物产一般同还原酮联系在一起出现,通过打破自由基链子显示施加抗氧化行动通过捐赠氢原子。 [translate]...
If a hydrogen atom bonds with another hydrogen atom( H-H), is this a hydrogen bond or covalent bond?Hydrogen BondsA hydrogen bond is a type of intermolecular force of attraction that is a stronger version of the dipole-dipole interaction (also an intermol...
Interestingly, if you compare the sizes of the particles involved (both the nucleus as well as the electrons), to the radius of the electron cloud surrounding the core, the latter is larger by orders of magnitude: Nucleus: 1.70 fm (Hydrogen), 11.7 fm (Uranium) Atom: 25 pm (...

a benzylphthalazinone of the general formula wherein R 3 is a hydrogen atom, resulting from (a), (b) or (c), with a compound of the general formula Q-R 3 , wherein Q is an atom or group which, upon substitution of the amide group, is split off together with its electron ...
1002.6 Å2, respectively. The NTD of AcrIF24 mainly interacts with the Cas7.6 f and Cas7.5 f subunits of the Csy complex. In the AcrIF24-Cas7.6 f interface, extensive hydrogen bond interactions are involved, e.g., H19AcrIF24:S73Cas7.6f, Y20AcrIF24:T78Cas7.6f, H19...
If the value of n=1, the quantum number l can have what values? Quantum Numbers of Electrons:Four quantum numbers are used to indicate the position of each electron present inside of an atom. The principal quantum number n indicates the electron's principal energy level, or shell. ...
