《无机化学》第6版张天蓝主编课后习题答案第一章原子结构1、υ=∆E/h=(2.034⨯10-18 J) / (6.626⨯10-34 J⋅s)=3.070⨯1015 /s; λ=hc/∆E= (6.626⨯10-34 J⋅s ⨯2.998⨯108 m/s ) / (2.034⨯10-18 J)= 9.766⨯10-8 m2、∆υ≥ h/2πm∆x = (6.626⨯10-34 kg⋅m2/s) / (2⨯3.14⨯9.11⨯10-31 kg⨯1⨯10-10m)=1.16⨯106 m/s。

其中1 J=1(kg⋅m2)/s2, h=6.626⨯10-34 (kg⋅m2)/s3、(1) λ=h/p=h/mυ=(6.626⨯10-34 kg⋅m2/s) / (0.010 kg⨯1.0⨯103 m/s)=6.626⨯10-35 m，此波长太小，可忽略；（2）∆υ≈h/4πm∆υ =(6.626⨯10-34 kg⋅m2/s) / (4⨯3.14⨯0.010 kg⨯1.0⨯10-3 m/s)= 5.27⨯10-30 m，如此小的位置不确定完全可以忽略，即能准确测定。

4、He+只有1个电子，与H原子一样，轨道的能量只由主量子数决定，因此3s与3p轨道能量相等。

而在多电子原子中，由于存在电子的屏蔽效应，轨道的能量由n和l决定，故Ar+中的3s与3p轨道能量不相等。

5、代表n=3、l=2、m=0，即3d z2轨道。

6、（1）不合理，因为l只能小于n；（2）不合理，因为l=0时m只能等于0；（3）不合理，因为l只能取小于n的值；（4）合理7、（1）≥3；（2）4≥l≥1；（3）m=08、14Si：1s22s22p63s23p2，或[Ne] 3s23p2；23V：1s22s22p63s23p63d34s2，或[Ar]3d34s2；40Zr：1s22s22p63s23p63d104s24p64d25s2，或[Kr]4d25s2；Mo：1s22s22p63s23p63d104s24p64d55s1，或[Kr]4d55s1；79Au：421s22s22p63s23p63d104s24p64d104f145s25p65d106s1，或[Xe]4f145d106s1；9、3s2：第三周期、IIA族、s区，最高氧化值为II；4s24p1：第四周期、IIIA 族、p区，最高氧化值为III；3d54s2：第四周期、VIIB族、d区，最高氧化值为VII；4d105s2：第五周期、IIB族、ds区，最高氧化值为II；10、（1）33元素核外电子组态：1s22s22p63s23p63d104s24p3或[Ar]3d10s24p3，失去3个电子生成离子的核外电子组态为：1s22s22p63s23p63d104s2或[Ar]3d104s2，属第四周期，V A族；（2）47元素核外电子组态：1s22s22p63s23p63d104s24p64d05s1或[Kr]4d105s1，失去1个电子生成离子的核外电子组态为：1s22s22p63s23p63d104s24p64d10或[Kr]4d10，属第五周期，I B族；（3）53元素核外电子组态：1s22s22p63s23p63d104s24p64d105s25p5或[Kr]4d105s25p5，得到1个电子生成离子的核外电子组态为：1s22s22p63s23p63d104s24p64d105s25p6或[Kr]4d105s25p6，属第五周期，VII A族。
