Question

What is the effective nuclear charge (Z_eff) of Copper (Cu)?

• A. Approximately 3.3
• B. Approximately 1.0
• C. Approximately 18.0
• D. Approximately 29.0

Hint:

Consider the shielding effect of inner electrons.

Answer 1

The Correct Option is A

Z_eff is the net positive charge experienced by an electron in a multi-electron atom. It can be approximated by Slater's rules, considering shielding effects of inner electrons.
