7.85

Explanation:

Z  is the nuclear charge, which is equal to the total number of protons in the nucleus. Use the periodic table to determine the number of protons in a copper atom.

To determine the value for S, start by writing out the electron configuration for the atom. The electron configuration for  Cu  is  1s22s22p63s23p63d104s1 . According to Slater's rules the subshells can be grouped as follows: ( 1s2 ), ( 2s2 ,  2p6 ), ( 3s2 ,  3p6 ), ( 3d10 ), ( 4s1 ).

In this case, the value of  S  is being determined for a 3d electron.  When the designated electron is in an  nd  group, rules ii and iii remain the same, but rules iv and v are replaced by rule vi.

According to rule ii, electrons to the right of the (3d) grouping do not contribute to the value of  S . According to rule vi, all electrons to the left of the 3d grouping, in this case (1s), (2s, 2p), (3s, 3p), contribute 1.00 each.
