    Quick note: Relativistic effects from the appearance of a 6th energy level, a 4f orbital, and significantly more massive nucleus contribute to why Lead is +2 vs +4. The explanation in video is supposed to be said simply. Describing an atomic model without using words "electrons," "protons," "neutrons," and "orbitals" and making it less than 2 minutes is why it is the way it is in video. I rewrote it several times over almost 2 months.

      @Ryan Barr It doesn’t have to do with gravity, but as he said in his comment with relativistic effects (with some quantum mechanics thrown in) Electrons in a particular atom are described by three quantum numbers, n,l,m. Electrons with lower quantum numbers are more likely to be found near the nucleus. Higher charges nucleus implies that the speed of the electrons will be higher. Because the speed of electrons in atoms with more charge (therefore more mass) is higher, and relativistically significant- according to special relativity they will have an increase in its relativistic mass, implying the orbit radius will become smaller. This is true in general for all orbitals.

      This decrease in radius would imply a higher ionisation energy, thereby contributing to the effect of making Lead likely to be in +2 state as the 6s electron pair becomes less likely to bond due to a combination of poor shielding by the 4f shell, relativistic radii contraction including lanthanide contraction and possible inert pair effect for the 6s2 electrons.

      I understand the post was unclear as it seems that it was the mass property of the nucleus that seemed to imply the effects of Lead’s favoured oxidation state, when it was rather that massive nuclei carry more charge, which cause the increase in relativistic speed which cause increase in relativistic mass of electrons.

      And really the only way we can prove this and see this is true is to solve the Dirac equation directly and use the S-Matrix formulation to find the bound states in the complex domain (which is intuitively asinine). For heavy atoms like Lead, dealing with an f orbital makes it a nightmare to deal with, especially since we no longer can use the non-relativistic Schrodinger equation.

By the way, have you noticed that in minute 10:25 where the kind and his mother are doing something by the table, behind the kid there is a door, and under it, crawling on the floor, appears something pretty weird, I don't know, it seems like a mouse for the color, but it's unfocused and moves pretty strange, could you tell me what it is or is it something supernatural? 😱

Now I know why I'm failing most of my classes and struggling to socialize. My early coping behaviors completely obliterated my brain and that is why I shouldn't be attending an outdated academic system that promotes stress and anxiety.

I'm hoping to not have to tell her about the lead as she gets older however I'm not sure that will be a possibility. she's super smart even still and I could see her asking too many questions lol so we will see on that! ty for ur information.
