REENU SIVADARSHINI.M
EFFECTIVE NUCLEAR CHARGE = Z -S Z= ATOMIC NO.
S CAN BE CALCULATEDBY THIS METHOD
S =[1s2 ] [ 2s2 2p6] [3s2 3p6 3d6 ] [ fe+2=24 electrons]
[n-2] [n-1] [n]
value of n=0.35;[n-1]=0.85 ;[n-2]=1;[n-3]=1
now no. of electron * respective value
s=[ 2*1] +[8*0.85]+[13*0.35] {in last set reduce one electron so 13 and not 14}
s=2 + 6.80+4.55
s=13.35
effective nuclear charge= 26- 13.35= 12.65
