Constants I Periodic Table Using the equation Zett 2-S and assuming that core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant,S,caloulate Zett for the 2p electrons in both ions. Consider the isoelectronic ions F and Nat Express your answers as integers. Enter your answers numerically separated by a comma. Submit Prey)An9Mer Request Answer Incorrect; Try Again; 5 attempts remaining Part c Ropeat this calculation using Slaters rules to entimate the screening constant, S Express your answers using two decimal places. Enter your answers numerically separated by a comma.Explanation / Answer
Answer:
You can estimate Zeff (Z*) using Slater's rules and the equation:
Z*=Z-S
assuming that core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant,S
Therefore,
for Na+: Zeff=11-2 = +9 (because 2p and 2s electrons are valance electrons and have a value of 0)
for F-: Zeff=9-2= +7 (because 2p and 2s electrons are valance electrons and have a value of 0)
