We’re being asked to calculate the effective nuclear charge (Zeff) of the 4s 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.

Step 4: Calculate for Zeff.
