Question

14.Calculate the effective nuclear charge of 3P and 3d eletron in Fe atom. ​

Answer 1

Answer:

Please give me a Brain mark

Explanation:

EFFECTIVE NUCLEAR CHARGE = Z -S Z= ATOMIC NO.

S CAN BE Calculated By 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
