Solving the puzzle of the periodic table - Eric Rosado

How did the periodic table of elements revolutionize our understanding of the world? What scientists contributed to the table we have today? Eric Rosado discusses the key people and discoveries that have molded our understanding of chemistry today.

This posts the fact that Mendeleev just wanted to create the periodic table. In fact, he was writing a school-book about chemistry and needed the table to explain certain behaviours of elements. Clearly, his work was remarkable....it's just important to show the whole framework

[ashia]

• Hennig brand

- isolated phosphorous from his urine


• Antoine Lavoisier ( father of chemistry )

- defined what an element was
- created a list of known elements in which they could be classified
- the first one who tried to put the puzzle together

• John Dalton

- weighed the elements and arranged the puzzle by weight


• Wolfgang Döbereiner

- combined elements to see how they reacted to each other

- bcs of him scientists discovered that elements belong to families that share similar properties


• Dmitri Mendeleev

- The one who put the puzzle together thus creating the periodic table

- ordered the elements base from atomic weight and known properties

- he also predicted elements that were not yet discovered

4:03 "The puzzle of the periodic table of the elements was salt"

I slept at the test thinking I would figure out all the
I failed

Not good compared to other ted videos, and you wipe out all Mendeleev's work saying that he dream it ! He did a lot of work and people think he is crazy before he got the answer !!!

After years and years and years... Now this fricking table makes some sense... Thanks!

[markrivas]

they got me watching this in Chemistry for a major grade 😭

[baseballsbetter]

Thank you for posting this. I have my chem final in literally 30 minutes

Um vídeo interessante, a parte que me deixou curioso foi o facto de como foi descoberto o fósforo através da Urina… Impressionante!!

[ShubhamThakkarShubhavatar]

Dmitri did not just dream about the table!
It took him more time and he worked with each and every element before classifying them!
This video does not display correct info!

Um video muito facil de se coompreender, muito interessante o fato de que a tabela periodica foi criada por um sonho

I took AP chem last year and watching this couldn't help but put a smile on my face. :) Thank you

[hobokengar]

Bravo Mr. Mendeleev...the world is a better place because of you...RIP.

Imagine discovering an element but Dmitrii knows more about the element than you do

[randallgyebi]

TedEd has a way of telling me things I already know in a fascinating way.

[kisho]

which are the similar properties per each group that specifie each corresponding column in the periodic table of elements?

[TheBarbedBard]

Maybe to you, but to my primary students this is accessible, inclusive and more importantly, far more engaging than the boring raft of text books currently available.

Comparing the periodic table to a puzzle, then to the game Tetris ; genius.
