A short history of the periodic table

Professor Davis is back! In this video he gives a short introduction to the concepts behind the most recognizable image in the study of chemistry - the periodic table of the elements.

This has helped me so much with my coursework. Thank you so much!

[@maksholowienko6307]

People watching this in chemistry lol

[@russelkingfuentes5601]

Same

[@aiahwko]

Me lol, I cant see the video from the telvision

[@vivian9252]

Ur the best prof tnx

[@mdb1239]

Mendeleev I think has been short shrifted big time. For chemistry this was the equivalent to the Standard Model of Physics today. He was the Newton&Maxwell&Einstein of chemistry.

[@gandalfhotty445]

this changed my life just as much as morbius did

[@rashmibalasooriya8979]

Can you please mention the resources where this information got.

[@odalysperez1433]

this helped me understand better, thankyou so much professor Davis!

[@AnujKumar-sx6ws]

What kind of properties did he notice similar after octet

[@jasonbourne5142]

Thanks, I wish someone had explained this to me in high school smh

[@AyushSharma-cm6jx]

Thanks 👍😍😻

I watched another video but whatever given here as Mendeleev's work were actually John Newlands' work. Mendeleev came in later. So, which is which??

[@ChemSurvival]

Newland's law of octaves was based on ordering elements without applying any empty spaces. He famously put nickel and cobalt in the same cell to make his scheme work without any gaps - something many consider an unforgivable oversight, since (1) cobalt and nickel are clearly not the same substance, and (2) new elements were being discovered at a clip of about one every two years at the time. If anything, Meyer would be considered a better challenger for the acknowledgement of the table's inventor, but Meyer's table only used about half the known elements at the time it was published, Mendleev's first offering had all 56, and included the 'eka-element' gaps that were proved to exist in short order. Basically if you want be remembered as the father of the modern table, 'go big or go home' is a moniker that you need live by.

There is a contradiction coming out btwn this reply from you and the video?

[@ChemSurvival]

@@TNG205 This is a considerably old video, and contrary to popular belief even professors can learn a thing or two over the years ;)

[@subhadeepde3013]

wow

[@ChemSurvival]

I take that as a 'like'? If so, glad you enjoyed the video. Pretty cool take on organizing the elements.

Thanks.

bread :)

[@misseon1]

No Democritus? :( Was interesting, thx!

[@demonstine2623]

Thanks Mr Rodwell

[@mobydick6420]

How did Mendeleev and his predecessors determine atomic weights?

[@jobinjohn7735]

They used their brains

[@Sterbann]

@@jobinjohn7735 smart

[@sithembilexulu4690]

Can't it be said that none of these are elements since they can be broken down further like in quantum

[@FS-qi1kj]

why didnt you mention Hennig Brand

[@ErikDev12]

real

[@bobstone623]

thanks

[@sithembilexulu4690]

It'll end up being a square

[@monorin8530]

Is it just teachers and desperate students here

[@earthlingwholivesonearth5009]

hi grade 8

[@mariegracericaplaza5882]

Ok
