Question

The contribution of other electrons present in1sorbital to ‘S’value is​

Answer 1

Answer:

In quantum chemistry, Slater's rules provide numerical values for the effective nuclear charge in a many-electron atom. Each electron is said to experience less than the actual nuclear charge, because of shielding or screening by the other electrons. For each electron in an atom, Slater's rules provide a value for the screening constant, denoted by s, S, or σ, which relates the effective and actual nuclear charges as -

{\displaystyle Z_{\mathrm {eff} }=Z-s.\,}Z_{\mathrm{eff}}= Z - s.\,
