many electron atom
解釋
多電子原子-
Metallophalocyanines ( mpcs ) are a kind of centrosymmetric planar organo - metallic molecules with an extensively delocalized two dimensional conjugated - electron system which show a relatively large third order optical nonlmearity, varying upon central metal atom substitution and other factors. other interesting properties of this molecule and many of its derivative products are their versatility, architectural flexibility and high environmental stability, which are very important requirements to implement photo - electronic applications
因其骨架結構特徵和可通過選擇中心離子、軸向配體和在酞菁環上引入功能性取代基等方法進行分子篩選與組裝得到具有特殊的物理化學性質和光、電、催化等功能的材料，而引起化學家和材料學家的濃厚興趣。 -
In this model the arrangement of bonds around the central atom is considered to depend upon how many valence-shell electron pairs.
在這個模型中，認為圍繞中心原子的化學鍵的排列取決于價層中電子對的數量。
