Problem: If core electrons completely shielded valence electrons from nuclear charge (i.e., if each core electron reduced nuclear charge by 1 unit) and if valence electrons did not shield one another from nuclear charge at all, what would be the effective nuclear charge experienced by the valence electrons of the following atoms?K

Recall that the effective nuclear charge is the force exerted by the nucleus onto an electron and is given by:

Zeff = Z - S

where Z = nuclear charge or atomic number and S = shielding constant. 

Potassium, K

  • Group 1A → valence electron = 1 e-
  • atomic number = 19
    • core electrons = 18 e-
    • valence electron = 1 e-
