According to slater's rule, calculate effective nuclear charge ( $Z_{eff}$ ) on last electron of $F^{-}$ .

Answer:

4.85

Solution:

To calculate $Z_{e ff}$ for F⁻:

Electron configuration: $1 s^{2} 2 s^{2} 2 p^{6}$ .

Shielding constant $σ = (2 \times 0.85) + (7 \times 0.35) = 1.70 + 2.45 = 4.15$ .

Atomic number $Z = 9$ .

$Z_{e ff} = Z - σ = 9 - 4.15 = 4.85$ .
