1.CO碳原子电子层结构为:1s22s22p1x2p1y,氧原子的电子层结构为:1s22s22p2x2p1y2p1z。碳原子2个未成对的2p电子可与氧原子的2个未成对电子形成1个σ键和1个π键,氧原子的1对已成对的2p2x电子对还可与碳原子的2pz空轨道形成一个配位键(用“→”表示)。所以CO的电子式为∶CO∶。碳氧原子之间实际上是共用3对电
1.CO carbon atom structure of the electron layer: 1s22s22p1x2p1y, the oxygen atom of the electron layer structure: 1s22s22p2x2p1y2p1z. Two unpaired 2p electrons of a carbon atom may form one σ bond and one π bond with two unpaired electrons of an oxygen atom. One pair of paired 2p2x electron pairs of an oxygen atom may also be bonded to a 2pz null of a carbon atom The track forms a coordination key (indicated by “→ ”). So the electronic CO is: CO:. Between the carbon and oxygen atoms is actually shared 3 pairs
