Calculate the screening constant of Fe. Will it be calculated just like we calculate for p and s block or will it be different for d block(Fe)?

Effective nuclear charge in iron for 4s electron & for 3d electron
Electronic configuration- 1s22s22p63s23p63d64s2
For 4s electron,
σ = (0.35 × 1) + (0.85 × 14) + (1 × 10) = 22.25
Z* = Z – σ = 26 – 22.25 = 3.75
For 3d electron,
σ = (0.35 × 8) + (1 × 18) = 19.75
Z* = Z – σ = 26 – 19.75 = 6.25
For 3s, 3p electron,
σ = (0.35 × 7) + (0.85 × 8) + (1 × 2) = 11.25
Z* = Z – σ = 26 – 11.25 = 14.75
For 2s,2p electron,
σ = (0.35 × 7) + (0.85 × 2) = 4.15
Z* = Z – σ = 26 – 4.15 = 21.85
For 1s electron,
σ = (0.30 × 1)  = 0.30
