Find the shilding constant $(σ)$ for the first electron entered into H to produce $H^{-}$

Options:

Answer:

Solution:

To find the shielding constant ( $σ$ ) for the first electron in H⁻, we use Slater's rules. H⁻ has two electrons in the 1s orbital. For an electron in the 1s orbital, the shielding constant is $0.30$ for each other electron in the same group. Thus, $σ = 1 \times 0.30 = 0.30$ .

The final answer is $0.3$ .
