Answer 1

Answer:

the shielding experienced by an s- or p- electron, electrons within same group shield 0.35, except the 1s which shield 0.30. electrons within the n-1 group shield 0.85. electrons within the n-2 or lower groups shield 1.00.

Hope this answer is helpful for you.

Answer 2

In Slater's rule, the correct arrangement of electrons according to the extent of their screening obeys the shielding effect.

Explanation:

• This is a general principle for the electron arrangement:-
• In Slater's rule - The actual charge is taken by the electron which is equal to the charge to the charge of the proton. but we have to minus the amount of charge from other electrons.
• Limitations of Slater's rule:-In the outer shell electrons do not shield the inner electrons. It is not true always.
• Even the electron in the outer s subshell will penetrate to the nucleus and would show a shielding effect.
• For each electron " the effective nuclear charge is defined as the actual nuclear charge (Z) minus the screening effect caused by the electrons intervening between the nucleus and the valence electrons".
