The elements had been listed and carefully arranged before Dmitri Mendeleev. They had even been organized by similar properties before. So why is Mendeelev's periodic table the one that has endured? Lou Serico explains via eka-aluminum, an element whose existence Mendeelev predicted years before it was discovered.

What's sad is that he spent the time to make the table so we'd have an easy reference so we wouldn't have to memorize them all but SCHOOLS STILL MAKE YOU MEMORIZE THEM ALL.
Actually in my chemistry classes you had a periodic table as reference for ever single test.
Kind of like in trigonometry you get a calculator.
Or in calculus you get a sawed off shotgun.......
true
Jonathan Hill exactly
@@jonathanhill6064 can I join your calculus class? please?
It's essential to memorize them because you won't have to look for a periodic table everytime, just like the multiplication table.

Mendeleev also created his table in such a way that the noble gases (which were discovered very late) could fit into the table without disturbing it. He was a true genius

00:38 - dmitri mendeleev
01:34 - he named an undiscovered element
01:41 - called eka-aluminum
02:28 - paul emile lecoq de boisbaudran discovered gallium, also known as eka-aluminum
03:07 - mendeleev predicted other elements aswell
03:49 - the element at number 101 was called mendelevium

People like that truly make me proud of being human. Human genius and insight at times is just unreal.
It's shame that as species we have so much more flaws than advantages.
Is that Trucy Wright?
***** Yup that's me.
Trucy Wright That's why we use our advantages to get rid of our flaws
Because of necessity. As you reduce or ensure necessities you reduce the apparent flaws.

The periodic table is one of the great devices for memorization. I recommend to you that you memorize the 1st 20 or 30 elements. By doing so, you will have most of the building blocks of chemistry memorized, similar to memorizing the main sequence of stars in re astronomy. The periodic table separates metals from gases, shows the groups who tend to have so many bonding combinations, etc.
In India, till grade tenth, we have to memorize that much also.
in the Philippines 7th graders have to memorize 50 elements
Why tf should we memorize?

For those wondering why Mendeleev choose sanskrit numbers like Eka ,Dvi ,Tri as prefixes for some elements, Wikipedia states that he heard from his friend Otto Von Böhtlingk , who was writing a book about the Sanskrit grammarian Panini,who had also similarly arranged the Sanskrit alphabets by their phonetic properties ; hence the reference
thanks for the info :)
Also his friend used some similar sanskrit words in some of his works on Sound waves
Honor to Dimitri Mendeleev
That wasn't his only achievement. He was so smart that he grouped the elements in such a way that it wouldn't disturb the group of noble gasses (group 18, period 1-7)
Noble gasses were not discovered at the time and when they were, an eighteenth group was created to not disturb the existing order.
Dmitri Mendeleev is one of my favorite scientists ever
Same
agree. how did create the table out of nowhere?
As a Russian I am glad that foreigners know about Mendeleev, because even in wikipedia it’s just called “periodic table” when in Russia we always call it “the table of Mendeleev”

This is no Genius, his descendant from the future came to him through time machine and gave him the Modern Table.
That is why he kept (V) before (Cr) irrespective of atomic mass. It can clearly be seen its a forceful act.
OR IF NOT,
HE IS LEGENDARY LEVEL GENIUS
Nice and instructing video! Thank you!
Too bad the Nobel prize committee at the time ,plotted to skip Mendeleev award.
Shame on them!
i have the peridoic table inside my sheets "whenever you look at a periodic table he will be staring back" YEAH no thanks
Shower curtains? Seriously, sheldon is the only one i think would put periodic table as a background.
We had a shower curtain with the periodic table a few years ago.

Dimitri was a born genius as he could see the vision before the vision was their.
whose?
Maybe the more thought provoking question is how do the elements know how to react to each other in the first place? Neutralialities, violatilities etc, since it is a table, just food for thought.
The periodic table in itself is ingenious. It arranges the elements based on atomic number, similar characteristics, valence electrons, electronegativity, ionization energy, and much more.
The discovery of periodic properties was pure genius!
Lou Serico's enthusiasm is epic! hes passionate!!! I wish he was my teacher in high school
Beautifully narrated!
;) Adorei... Me apaixonei por todos os vídeos desse canal. Muito bom!!! Veio aquele momento de decepção quando Mendeleev não recebe nenhuma nomeação pelo menos. Mas aí vem o contraste do elemento em sua homenagem, o mendelévio :D

Obviously his Mama saw something very unique about him to go to such trouble to get him educated.
Thank you Mother of Dmitri
More chemistry and psychology please!
That fact he managed to make almost prefect predictions is nothing short of incredible. I love science.
Great video; thanks!
Eka, pronounced 'aeka' in bengali, means 'alone'! Glad to see some of such words being used in science community.
Eka was a sanskrit word
Eka - Sanskrit - meaning 'One'
The gallery of pics showing all noble prize winners showed Gandhi as one of them. For your information he never won a Nobel prize
EXACTLY!
And he was in that awful Dictator movie, too. Ghandi sucks!
How exactly did gandhi nuke ur fudge cities? Go get a history book idiots.
@@BatMandor He's referring to a glitch in the video game "civilization" where, when Gandhi researches the Manhattan project, his aggressiveness level is supposed to drop by one point. The problem with that is, Gandhi already has the Lowest possible level of aggressiveness. So, instead, the game sets it to the maximum level. Which results in him nuking everybody in the game.
Thanks for making me understand what those empty spots are! 😍
thank you. excellent video

As far as I have heard the gaps were originally left to make sure that the other elements having similar properties fall in the same column.

This man is my hero. I love this table and this man. Mendeleev, you absolute genius!
best youtube video i have ever seen, truly, it is the best.
I would name an element LouSericom. That was excellent!!
Thank you, you helped me understand the evolution of the periodic table for my science exam

great video! keep it going
I had an exam for this!! This guy saved me
So is anyone else watch this because they missed it in class and they don’t want a F or is it just me
..just me okay🤷🏽♀️.
Mendeleev made his own periodic table, but the table that we use today , Modern Periodic Table , was not done by Mendeleev. It was done by Henry Mosley and 3 other scientists. But the stepping stones for the Modern Periodic Table are 100% derived from Mendeleev's Periodic Table.
Things like classification of elements in the form of periods and groups and also using a tabular form. He also classified the elements on the basis of oxides and hydrides and also corrected the atomic mass of many elements. Obviously, the greatest part of his Table was leaving empty spaces for future elements to be placed.
Even after how great the table was it had some serious disadvantages:-
1)It could not explain the position of hydrogen . This is still a problem in Modern Periodic Table, but we have kind off resolved by giving hydrogen a completely different position in the Modern Periodic Table. You might have observed that all elements touch each other in the modern periodic table except hydrogen.
2)The elements were classified on the basis of their atomic mass. If arranging elements using atomic mass sounds wrong to you or you have a question as to why atomic mass is not good for classification, then let me explain. If we use atomic mass for classification of elements, then we will also have to include the isotopes (elements with same atomic number, but different atomic mass. Eg. Hydrogen has 3 different isotopes)of all elements in his Periodic Table . If we had to do this then his table would be incredibly large and would be impossible for remembering.
3)Since he used atomic mass for classification, others questioned him as to why he didn't include all the isotopes of all the elements.
These 3 are the reasons why we don't use Mendeleev's Periodic Table
Thank you!!! Nice video!!!
on what bases he left gaps in his periodic table , I mean how he was able to predict there was a element missing and also how he predicted it's physical and chemical properties . plz tell fast I am very curious
It's most amazing that Dmitri Mendeleev saw the Periodic Table in a dream. “Knowledge is a light which God casteth into the heart of whomsoever He willeth." ~ Bahá’u’lláh, Baha'i Faith

Isn't there some relation between musical octaves and the construction of the periodic table as well? I remember hearing it in chemistry, and I thought it was a very interesting story. I could be wrong though...
Mendeleev:
Paul Emile Lecoq de Boisbaudran: _surprised Pikachu face_
The interesting thing is that Mendeleev discovered the Periodic Table, but didn't invent it; none of us did. Every element in existence already fit perfectly together in a massively complex 3-4 dimensional puzzle. Humans found something that was already intricately and *amazingly* designed by God.
God made the elements
Humans made the table
@@marceltelang7825 It was more like we discovered it. All the elements fit together amazingly well; we just figured out how they did it.
@@dmangelsm1188nope, we invented the periodic table
😂
finally my science teacher got us something good to watch
the voice of the narrator made me remember of my late chemistry teacher, old, wise, funny and genius.....
Well, students discover more elements than the scientists
Eg: potasscum, sodadium
😉
Mendeleev was a sheer genius...
Bro, what. Who's gonna be able to do something as great as this in the next 200 years?
This is so wow!
Class 10 Science chapter.Wish me luck for Boards!!
here is the problem the table which you are referring to on cups t shirts etc. it is the modern periodic table and it was developed by Henry Moseley and is based on atomic number whereas the one given by Mendeleev was based on atomic mass reason why it had so many anomalies so Moseley just improvised it
Tanvesh Rele Exactly !!! I was searching for this comment or else I would have done it myself...
Dr Santosh Dharmadhikari Wow you're PhD !!! Great to hear this from a professor
Tanvesh Rele Lol no no I m a medical doctor ... :)
Still he is called the father of periodic table. And the video credited him for successfully predicting new elements. Also the new periodic table was developed after the new concept of atomic structure was proposed by Neil Bohr in 1913. Mendeleev's died before that. The new one was based upon his work.
He was the first to classify all the elements known...he led the way for the modern periodic table..otherwise, it would not be created
This saved my day
This litterly creaking me up 😂😂😂😂 periodic table on anything I love THIS!!😂😂😂😂
The only way these videos get so many views is because students are told to watch it
