摘要: 基于“固体与分子经验电子理论”(EET),分析了Cu、Ag、Au的价电子结构,计算了一组表征金属单质性质的价电子结构参数统计值E'A,T'm ,利用价电子结构参数统计值讨论了Cu、Ag、Au的熔点问题。计算结果表明,E'A 值越大,其对应金属的熔点越高,且E'A 的变化趋势与实验相吻合;Cu、Ag、Au熔点的统计值分别为T'Cum=1351.0K、T'Agm=1126.2K、T'Aum=1305.0K,相应的实验值偏差依次为0.41%、8.82%、2.33%。

Abstract:  

Based on the empirical electron theory of solid and molecules (EET), the valence electron structures of Cu, Ag, and Au were analyzed. The statistical values of valence electron structure parameters E′A and T′m, which characterize the properties of metal single element, were calculated. Furthermore, melting points of Cu, Ag and Au were calculated by the value of T′m and E′A. The calculations results show that the melting point of corresponding melt is higher when the value of E′A is bigger, and the change trend of E′A in accordance with the experiment. The statistical values of melting point of Cu, Ag and Au were T′Cum=1 351.0 K, T′Ag m=1 126.2 K, T′Aum= 1 305.0 K, respectively. The corresponding deviation of experiment values are 0.41%, 8.82%, 2.33%.
