Question

A student reported the radii of cu,cu+ and cu+2 as 96,122 and 72 ppm respectively ppm you agree with result

Answer 1

No ,i do not agree with the result.

Cu = 122 Pm

Cu+ = 96 Pm

Cu2+ = 72 Pm

Explanation:

As the cu loses the valance electron and becomes cu+ its radii decreases, as the molecular forces gets stronger ,

further if another e is removed the radii further decreases.

the values of radii will be :

Cu = 122 Pm

Cu+ = 96 Pm

Cu2+ = 72 Pm
