Slater's Rule and Shielding Constant

Front

What is the shielding constant (σ) for a 3s electron in a phosphorus atom (P, atomic number 15) according to Slater's rule?

Back

The shielding constant (σ) for a 3s electron in a phosphorus atom can be calculated using Slater's rules, which take into account the contributions of other electrons in the atom.
