" 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...
It is interpreted that the spontaneous bond contraction, estimated at 12%–14%, strengthens the binding energy and hence the hardness and Young's modulus at the surface. The lone-pair weak interaction claims the responsibility for (i) the high elastic recovery, (ii) the lower Raman frequencies...
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,...

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 ...

Description of lone pairs in conjugated systems is based on the strength and sign of orbital interactions around the ring. Simple models for bonding in copper clusters are tested, and the bonding of O2 to Fe(II) in hemoglobin is described. Arguments made are supported by HF, B3LYP, and MP...
The covalent bond is drawn as a dash in a Lewis structure to distinguish the bonding pair from the lone pair electrons. Lewis structures show the nonbonding electrons as pairs of dots located about the atomic symbols for the atoms. The Lewis structures of four simple organic compounds—methane...
