Inert-pair effect

Postby JTieu_1L » Tue Nov 03, 2020 9:29 am

Does anybody understand the inert-pair effect and why it occurs?

I believe that inert pair effect is common in the 15-17th group elements and usually is it because the inertness of the inner electrons do not have good shielding. But, I am also wondering the same thing because I do not know much about this topic.

I am also unaware of this effect. It would be nice if someone could explain it :)

In simple terms, the inert-pair effect is refers to the tendency of valence electrons to remain unshared in the compounds of post-transition metals. Here is a website that explains it well: https://courses.lumenlearning.com/chemi ... 20elements.

Hope this helps :)

The inert-pair effect has to do with the tendency of the outermost two electrons in the s orbitals to remain unshared in post-transitional metals, and it explains why heavier atoms like Sb and Pb have a difference in the oxidation state of 2. But since professor Lavelle mentioned we only need to know until the first row of transition metals, I don't think we need to know this concept very thoroughly.

Hope it helps!
