应用新发展的金属价键理论对金属Ag的电子结构和性质进行了系统研究。我们采用单原子状态自治法确定金属Ag的电子结构为[Kr](4d_n)~(5.33)(3d_c)~(4.53)(5S_f)~(1.14)。依据这种电子结构计算了晶格常数、结合能、势能曲线、体弹性模量和线热膨胀系数随温度的变化,理论值与实验值均符合较好。本文列举了金属Cu和Au的原子状态参数,键参数和主要物理性质,金属Cu的电子结构为[Ar](3d_n)~(4.89)(3d_c)~(4.77)(4S_f)~(1.34),金属Au的电子结构为[X_c](5d_n)~(4.65) (5d_c)~(4.71)(6S_c)~(0.62)(6S_f)~(1.02);分析了贵金属Cu,Ag和Au的共同特点和彼此间的差异;并以简明的方式说明价键理论和能带理论的要点,对比了两种理论所得金属Cu,Ag和Au的准电子占有数(QEO),它们彼此非常相近,这充分显示了价键理论与能带理论彼此是可以沟通的。
The electronic structure and properties of metal Ag have been systematically studied with the newly developed metal bond theory. We determined the electronic structure of Ag by single atom state autonomy [Kr] (4d_n) ~ (5.33) (3d_c) ~ (4.53) (5S_f) ~ (1.14). Based on this electronic structure, the calculated lattice constant, bond energy, potential energy curve, bulk modulus and linear thermal expansion coefficient with temperature changes, the theoretical and experimental values are in good agreement. In this paper, the atomic state parameters, bond parameters and main physical properties of metals Cu and Au are listed. The electronic structure of Cu metal is [Ar] (3d_n) ~ (4.89) (3d_c) ~ (4.77) (4S_f) ~ The electronic structure of metal Au is characterized by the common features of Cu, Ag and Au, and the metal structure of Cu, Ag and Au is analyzed. The electronic structure of Au is [X_c] (5d_n) ~ (4.65) (5d_c) ~ (4.71) (6S_c) ~ (0.62) (6S_f) ~ And the difference between them; and concisely describes the valence bond theory and band theory points, compared the two theoretical Cu, Ag and Au metal quasi-electronic possession (QEO), which are very similar to each other, which fully shows The valence bond theory and the band theory can communicate with each other.
