Inert pair effect

In certain groups of the p-block, the heavier members are generally observed to be stable in a lower oxidation state (that is lower than the group oxidation state by two units). Inert pair effect explains why this happens so! Timestamps 00:05: Where do we see the effect of inert pair effect? 01:35: What is shielding? 02:50: Do all inner electrons have same shielding capacity? 03:35: What does shielding depend on? 04:25: Which of them has better shielding power: s or p orbital and why? 05:55: Order of shielding power 06:40: What is the consequence of poor shielding?
