" Lone bond pair" 通常不是一个常见的化学术语。在化学中,我们通常谈论“lone pair”或“lone pair of electrons”,它指的是分子或离子中未参与成键的非键合电子对。这些电子对位于一个原子的周围,并且没有与其他原子共享。 以下是一些具有孤对电子的分子或离子的例子: 1.水 (H2O): 氧原子有两个未参与成...

As the pair resolve to make their peace with the ghosts haunting them as they stay in the town of Matera, Bond at Madeleine’s encouragement goes to say farewell at the grave of Vesper Lynd, his great love from Casino Royale. But Bond is almost killed by a bomb secreted in her tomb,...
It is shown that bond contraction and nonbonding lone-pair interaction dominate at nitride surfaces. The maximum elastic recovery of a nitride surface was found to be 100% under a relatively lower nanoindentation load (<1.0 mN) and the hardness of the surface was found to be 100% higher ...
And Britt Ekland, who manages to find a way to be somewhat endearing and the lone bright spot despite her role as James Bond assistant Mary Goodnight, a stereo-type dumb blonde dressed in a bathing suit in unlikely situations, and who is made to suffer the humiliation of being pushed in ...

VESPR (Valence Shell Electron Pair Repulsion Theory) 在复习原子结构的时候我们反复说过它们的最外一层都是电子,都是负极,而同极相斥,因此每一个原子之间都得保持一定的距离。当多个原子被放到一起,每一个原子都尽量给彼此更多空间(就像社恐的我和我的社恐室友)。
Different electron lone pair representations are related by the pictorial rules and have stability understood in terms of Walsh's rules. Symmetries of conjugated ring systems are related to their electronic state by simple mathematical formulas. Description of lone pairs in conjugated systems is based ...
While a single covalent bond is created when two atoms share an electron pair, multiple bonds are formed when two or three electron pairs are shared. Some bound atoms have extra pairs of electrons not involved in bonding. Lone pairs of electrons are what they're called. The arrangement of ...
Grinning through the driver`s window was the foxy face with little tufts of hair high on the cheekbones, like a pair of spare eyebrows. [James Bond Junior, Chapter 14] Behind the bar was a peroxide blonde who pulled beer dreamily as she conversed with a red foxy-faced man sitting on ...
