We’re being asked to calculate the effective nuclear charge (Zeff) of the 4s electron and 3d electron in a copper (Cu) atom.
Recall that the effective nuclear charge is the force exerted by the nucleus onto an electron and is given by:
where Z = nuclear charge or atomic number and S = shielding constant.
For this problem, we need to do the following steps:
Step 1: Determine the atomic number.
Step 2: Determine the electron configuration and group them by n-values.
Step 3: Calculate for the shielding constant using Slater's Rules for a 4s electron and 3d electron.
Step 4: Calculate for Zeff for a 4s electron and for a 3d electron.
Calculate Zeff for the 4s electron in a copper atom, Cu and then Calculate Zeff for a 3d electron in a copper atom, Cu.
