Plz solve this ... i think the answer written here is wrong plz check... glrde01 the 285, first has higher etfective nucge 3. find out the shielding constant

from the practice problem continuation

u may practice these problem also

The formula to be used is:  Z* = Z - S  where:  Z* = effective nuclear charge  Z = atomic number of Fe= 26 S = shielding  Let us first calculate S using Slater's rule.  *Write ...
