How does shielding happen?

Shielding happens when electrons in lower valence shells (or the same valence shell) provide a repulsive force to valence electrons, thereby "negating" some of the attractive force from the positive nucleus.

How to Calculate Shielding Constant for Ns Electron?

Shielding Constant for Ns Electron calculator uses Shielding Constant for Ns = (0.35*Number of Electrons in Same Group)+(0.85*Number of Electrons in n-1 Group)+(1*Number of Electrons in n-2 Group and Counting) to calculate the Shielding Constant for Ns, The Shielding Constant for Ns Electron formula is defined as the effective shielding of electrons in Ns orbital. Each electron is said to experience less than the actual nuclear charge, because of shielding or screening by the other electrons, which is given by Slater's rules. Shielding Constant for Ns is denoted by S_Ns symbol.

How to calculate Shielding Constant for Ns Electron using this online calculator? To use this online calculator for Shielding Constant for Ns Electron, enter Number of Electrons in Same Group (E_n), Number of Electrons in n-1 Group (E_n-1) & Number of Electrons in n-2 Group and Counting (E_n-2) and hit the calculate button. Here is how the Shielding Constant for Ns Electron calculation can be explained with given input values -> 4.4 = (0.35*2)+(0.85*2)+(1*2).

FAQ

What is Shielding Constant for Ns Electron?

The Shielding Constant for Ns Electron formula is defined as the effective shielding of electrons in Ns orbital. Each electron is said to experience less than the actual nuclear charge, because of shielding or screening by the other electrons, which is given by Slater's rules and is represented as S_Ns = (0.35*E_n)+(0.85*E_n-1)+(1*E_n-2) or Shielding Constant for Ns = (0.35*Number of Electrons in Same Group)+(0.85*Number of Electrons in n-1 Group)+(1*Number of Electrons in n-2 Group and Counting). Number of Electrons in Same Group is the number of electrons in the same valence shell or nth cell, Number of Electrons in n-1 Group is number of electrons in the first group after the required electron group & Number of Electrons in n-2 Group and Counting are the remaining electrons in the lower groups.
