A) Cu
B) Li
C) K
D) Na
Correct Answer: D
Solution :
Since, the radial probability distribution curve has 3 peaks, it means that for it \[n=3\]and \[l=0.\] Moreover, it has two radial nodes ie, \[n-l-1=2\] (which also satisfied previous condition, ie, \[3-0-1=2.\]Hence, the valence electron of the metal must present in \[3s-\]orbital. The outer electronic configuration of the given metals is \[_{29}Cu=3{{d}^{10}}4{{s}^{1}}\] \[ & 3Li=2{{s}^{1}}\] \[_{19}K=4{{s}^{1}}\] \[_{11}Na=3{{s}^{1}}\] Thus, the given wave function corresponds to the valence electrons of the sodium metal.You need to login to perform this action.
