Shielding Effect in s and p Block Elements
The shielding effect refers to the ability of inner electrons to shield the outer electrons from the full nuclear charge. In s and p block elements, the shielding effect increases along the period.
Explanation:
- In s and p block elements, as we move across a period from left to right, the number of protons in the nucleus increases. This leads to a stronger nuclear charge which attracts the outer electrons more strongly.
- However, the shielding effect also increases along the period. The inner electrons shield the outer electrons from the full nuclear charge, reducing the effective nuclear charge felt by the outer electrons.
- As we move across a period, the number of inner shells remains constant, but the number of electrons in the same shell as the outer electrons increases. This increases the shielding effect.
- Due to the increasing shielding effect along a period, the outer electrons in s and p block elements experience less attraction from the nucleus compared to the previous element in the period.
Impact:
- The increasing shielding effect along a period in s and p block elements results in a decrease in the effective nuclear charge felt by the outer electrons.
- This leads to a decrease in the attraction between the nucleus and the outer electrons, which affects various properties of the elements such as atomic size and ionization energy.
In conclusion, the shielding effect in s and p block elements increases along the period due to the increasing number of inner electrons that shield the outer electrons from the full nuclear charge.
