Two organic compounds that ordinarily would not readily react with other easily both bond to an atom of palladium.

钯原子可以轻易地把两种正常情况下不易反应的有机化合物联接起来。

OK, then it says draw a single bond from each surrounding atom to the central atom, and subtract two valence electrons.

后将中心原子与其相邻原子之间，连上单键，然后减掉2个价电子。

A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion.

一个原子失掉一个电子来形成一个正离子，另一个原子得到一个电子来形成一个负离子的化学键。

All right, so the type of bond energies that we can go and look up in tables are individual atom bonds, H-H, F-F, and the like.

好的，键能的类型,我们能够在表中查到,都是独立的原子键，H-H，F-F以及类似的。

Whereas in molecular orbital theory, what I'm telling you is instead we understand that the electrons are spread all over the molecule, they're not just associated with a single atom or a single bond.

而在分子轨道理论里，我要告诉你们的时,我们任为电子分布在整个分子中,它们不仅仅是和,一个原子或者一个键有关。

By tuning the laser very precisely to the frequency of one particular sort of bond (such as that with a heavy carbon atom at one end), a molecule containing that bond can be shaken up.

The researchers caught an intermediate step in the process by which hydrogen is removed from tryptamine, namely the point at which a proton disappears from a carbon atom as the carbon-hydrogen bond breaks.
