Question

consequences of shielding effect?

Answer 1

The shielding effect is when the electron and the nucleus in an atom have a decrease in attraction which changes the nuclear charge. An example of shielding effect is in nuclear fission when electrons furthest from the centre of the atom are pulled away.

⭕ The electrons in the inner shells acts as a screen or shield between the nucleus and the electrons in the outermost shell.

⭕ This is called shielding effect or screening effect.

⭕ The larger the number of electrons in inner shells, greater is the screening effect and smaller the force of attraction. Thus, ionisation enthalpy decreases.

⭕ Thus, shielding effect is inversely proportional to ionisation enthalpy.
