 Effective Nuclear Charge

Could anyone provide me with a proper definition for Effective Nuclear
Charge? I've been searching around the 'Net, and I found data but no
definition.

TIA,

Daniel

Hello ,

  You should consult a book of inorganic chemistry, such as Wilkinson
Advanced Inorganic Chemistry.
 What is important to know is that the effective charge : Zeff is :

        Zeff = Z - sigma

  Z = charge of the atom
  sigma = screen constant

 It means that an external electron does not see the true charge of the
nucleus, but an effective charge, that is quite obvious.

sigma  given in table may be calculated.
