What is \'inert pair effect\'? |
|
Answer» Reluctance of iner s electrons to participate in bond formation is celled inert pair effect By sheilding and screening effect the core orbital electron are not participate in reaction or bonding due to increase in effective nuclear charge ,this is called inert pair effect In the elements of 4th, 5th and 6th period of the p-block the electrons present in the intervening d and f-orbitals do not shield the r-electrons of the valence shell effectively.As a result, {tex}{{ns}^{2}}{/tex} -electrons remain more tightly held by the nucleus and hence, do not participate in bonding. This is called inert pair effect. |
