This formula uses 4 Variables
Variables Used
Shielding Constant for Ns - Shielding Constant for Ns is the effective shielding of electrons in Ns orbital.
Number of Electrons in Same Group - 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 - 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 - Number of Electrons in n-2 Group and Counting are the remaining electrons in the lower groups.
STEP 1: Convert Input(s) to Base Unit
Number of Electrons in Same Group: 2 --> No Conversion Required
Number of Electrons in n-1 Group: 2 --> No Conversion Required
Number of Electrons in n-2 Group and Counting: 2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
SNs = (0.35*En)+(0.85*En-1)+(1*En-2) --> (0.35*2)+(0.85*2)+(1*2)
Evaluating ... ...
SNs = 4.4
STEP 3: Convert Result to Output's Unit
4.4 --> No Conversion Required
FINAL ANSWER
4.4 <-- Shielding Constant for Ns

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 SNs symbol.
