The periodic table organizes elements into groups and periods based on their chemical and physical properties. Elements in the same group share similar characteristics, like reactivity. The table is divided into metals, nonmetals, and metalloids, each with distinct properties. Key groups include alkali metals, alkaline earth metals, halogens, and noble gases.
Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

Thanks
Thanks
bro you’re a god darn Saint. Thank you for taking the time to do this.
Trying to figure out why people would ever dislike these? Or are they just protesting against school?😂😂😂
its bots and other organizations who make vids like this
people can be bad minded
Understanding & Common Sense is sadly not so common nowadays. Instead its replaced with fear & ignorance on average.
Some people just find these super confusing
bruh nobody rlly like school smh
I learned a lot in a few minutes . your method is better than the chemistry teacher.
Hlw
@@dharmaraosorde1701 Amen!!! I'm also off tress...
2nd thought. Technically, he is now a chemistry teacher...🤷🏽♀️
Facts
i completely agree
True fact bro 😊
This has been a life saver for me!!! Thx u sm
2020 kids where u at?
Hi
Same here.
This is helping me a lot in our online chemistry class. You're awesome!
Pay no mind to the hate comments. You're an excellent mentor. Keep the vids coming :-)
@bobgigahertzman what?
Ayy
who? who hates him??? He is literally my saviour 😭🤌
thank god I watched this video because all of my knowledge about elements argon .
That was hot
@@youseriousb3362 facts
what does that mean???
@@theUnmeshraj argon, are gone- its a pun I think

who's here from school
Meee!!
Who isn’t here from school 😂
@@mcm7119 facts tho lol

@@mcm7119 me. Im actually only in 4th grade, but i love science
thank you !! this helped me a lot for studying for my first chem test !

I was gonna make a sodium joke, but Na.
Ok I have a different one:
2 scientists walk into a bar. One says, "I want H20." The other says, "I want H20 too".
The second one dies.
Ok, here's a potassium joke. What, you don't want to hear it? K.
Periodic table puns are funny, AmIrITe?
I didn't get it.
He asked for “H20 too”. It sounds like H2O2 which is hydrogen peroxide and I think can kill you
ha...get it now
lolol this comment is so perfect
It's funny
Thank you so much! This video is awesome and straight forward.
It's an oldie but a goodie
thank you khan academy
who is here for school 2020? Mac kids where u at
Taylor Kotch ‘’f
meee- he sounds so young lmaooo
@@_buany8701 I don’t think that’s Sal, if you watch some of his videos back in 2010 or something, he still sounds the same.
this video was perfectly informative
There are four blocks namely S, P, D and F in the Modern Periodic table. Element are classified into four Blocks on the basis of valence shell electronic configuration. Those elements which have their outer most sub shell is S, constitute to form S block. Similarly p, d and f blocks are formed on the basis of outermost valence subshells p, d and f.
Yeah this is also one of the basis on which periodic table is classified
I am now learning and memorizing something I will forget after a few couple of days :)
Hi
Fir real!! I don't see why we would ever need this after we graduate or anywhere out of school. These stuff are useless to learn.
@@eddiehenriquez3990pretty useful when you're a chemist
@@eddiehenriquez3990 it's useful you fool. Plus it's basic knowlege which your should be aware of.
This really really helps me i got a 50/50 in exam thx alot i could not done it with you making this vid imma sub keep up the good work
i never missed any topic of my syllabus becoz of this
I remember dumbass 3rd grade me was trying to learn this to be cool
thanku só much ... GOD bless u
I'm 11 years old and in the future I want to be a cardiologist and this video is helping me a lot
Me 2 , good luck bro :)
Hoyooo kid.. happy to see u looking forward for ur dreams at this age ..i hope u get all the blessings u deserve...keep working hard lil kiddo...u will surelyy achieve..may the lord bless uh !! enjoy ur childhood too kid ❤😢

Большое спасибо, очень интересные видео!
Да да да! :)
Да, это правда!
Who has chemistry exam tomorrow?
I do

Oh my god you are a life saver!
Excellent
Saw this as the first video and subscribed.
Thanks sir...u explain waaayyy beter than my chemistry teacher❤❤
❤Thx bro u just saved my life 😅
concise !
I’ve learned more from this video than I have all year in chem
This video was so helpful for me. Great explanation!
Thanks for helping me Ace gen chem. Also, your videos on some calculus subjects were incredibly helpful. Khan is the OG.
Yes, im in 6th grade and we are learrning this. Very helpful!
oh are u now big fella?
12?
I r in Secund grade rite now al
aslo
CAT Club Nice. I'm in 7th
So how's 7th grade?
Very clear and concise.
this helped me a lot, thank youu!
I'm always whacking all your periodic table videos I love them
Thanks for making me understand elements better.
Thank you ☺
Thanks for sending this message
Very helpful for Revision for my daughter's test
Love it , give us more and more knowledge
Thank you so much this info will help on my science test
Are their any unclassified/secret, non recognized or not published elements in the periodic table ?
I have a midterm today thanks
Learned Alot with this explanation more than my teacher's explanation about the topic
I’m about to start this unit , next class in PRE -AP Chemistry 1 which is on Thursday we finished our unit about Isotopes , Average Atomic Mass as well as writing the isotopes in hyphen and nuclear notation
Thank you so much 😁
Great video
Thankyou. It helped me make a concept about periodic table.
1. Locate the metals, non-metals and noble gases in the Periodic Table of Elements. Color the area with metallic elements blue; the non-metallic elements yellow and the noble gases green.
I got lot out of this. Thank you.
helpful
ohhhhh
great video really understood everything
Helpful
nice explanation

Mrs. brewingtons class where u at
wow this is cooooooooooooooool
No
Thanks 😊
Very well done
Where are my 2020 online students at?
thanks for the video it was really good I used it for my homework
Im learning
In my chemistry lecture, we actually discussed how hydrogen is indeed a metal. There is a reason it is placed where it is on the periodic table. :)
Can u explain?
thank u for this.. very helpful
np bby
Good man
🔥🔥🔥👍👍👍
good
what are sets "noble metals", "solenoids", "semimetals", "rare earths", ...?
guys lets spam this youtube video!
Im a little bit confused of groups and family in periodic table . Are they d' same? Why other element in this video doesn't have family? Like the group 3-12.
I would tell you an electron joke but it would just be negative
@Michael Jordan 😂😂lol
lol
Ty for helping me
My chem teacher got mad at us so he just didn’t teach us this
what about the bottom part of the periodic table the elongated one you missed that section.
if you watched the video you'd know that he said he didn't have enough room to cover it.
lol
Thx a lot
this is yes
when ur in 7th trying to learn more about the periodic table and memorize them all 👏😫😩 well i learned numbers 1-58 😃
Facts
can someone tell me about mendeleev and how he ordered the periodic table.
Lemon Bleach search " periodic table explained" and check out the video made by Crash Course.
That'll help you
HeadHome Gamer - Its all good i done the exam on that all ready.😊
He ordered in amazon
He's the culprit who responsible for this mess
Nice joke vanapalla Chaitanya
Me
I need this I start 8th grade casp test tomorrow which cover 6th through 8th and we can say 7th sucked last year
I think the line that separates the metals and nonmetals should start on top of boron then we zig zag (I'm not sure tho)
I want some more brief explanation
Wow..
