WebNov 17, 2024 · The screening constant is represented by 'o' (sigma). For example, across a period the electrons enter the same shell. Thus, shielding due to inner electrons remain same. Down a group, a new larger valence shell is added which increases the inner electrons and thus the shielding effect increases. Web2. The decrease in force of attraction on valence e – due to inner shell e – is called screening effect or shielding effect. (i.e. total repulsive force is called shielding effect.) 3. …
