Mineral Groups

Mineral Groups

Mineral Groups. Nearly 4000 minerals have been discovered and named; however, no more than a few dozen are abundant. These few dozen makes up most of the rocks that comprise Earth’s crust. This is why we call them the rock-forming minerals.

一 、 d 軌道的能級分裂

1923 ~ 1935 年貝特和範弗萊克提出晶體場理論。 晶體場理論認為 :絡合物中中心原子和配位體之間的相互作用,主要來源於類似離子晶體中正負離子之間的靜電作用。這種場電作用將影響中央離子的電子層結構,特別是 d 結構,而對配體不影響。. 一 、 d 軌道的能級分裂. 二 、 d 軌道中電子的排布 — 高自旋態和低自旋態. 三、晶體場穩定化能. 四、絡合物畸變和薑 – 泰勒效應. z. y. z. -. +. -. +. +. -. x. x. y. +. -. -. +. +. -. d xz. d xy. d yz. -. +.
