(As a group descends, the increasing shielding and increasing atomic radius outweighs the increasing nuclear charge. Hence, electronegativity decreases.) 其次, 在同一周期中,从左到右酸性越来越高(因电负性) 在同一族中,从上到下酸性越来越高(因大小) 是的。从左到右和从上到下的规则看起来是反的。以...

aWhile Fault Group 2 MC malfunctions take the same effect as Fault Group 1 malfunctions, they result in the termination of a movement cycle of MC that is in progress. Performing another cycle start of mould carrier is not possible! The horn will sound and the red signal lamps will start...
This characteristics are similar to CaBiO2Cl36, Bi2O2[BO2(OH)]23, and so on; (ii) In SO422 group, a significant hybridization can be observed among S 3s, 3p and O 2p orbits located at 223 eV and 219 eV, respectively. The hybridization in VB favors for the formation of stable ...
Neighbouring group participation (i.e., anchimeric assistance) : Since the rate of hydrolysis is much faster than that of 1^@ RX, it follows that E(act) of both steps is lower than E(act) of one step (SN^2) mechanism for 1^@ RX, As the EN of C is
