Question

Which of the following graphs represents the radial charge density for the electron of outer most sub shell of $C{u}^{2+}$?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

The number of maxima in the radial charge density curve is $(n-l)$
For a 3d electron, n = 3 and d = 2
Hence, $n-l=3-2=1$
There will be only one maximum in the curve for a $3\text{d}$ electron.
