2021.. after a decade he is still the best chem teacher. Helping students like me across the globe. I am preparing for a hardass exam and this is the most helpful channel I have come across. Incredible. Better than any paid course or even Uni professors.
This channel should be trending now because of Covid and online classes boom.
This man is amazing. I wish UA-cam had been around during my college years...would have saved me many tears.
very true
britishTRIGGERED chick 9th as in high school? Cause me toooo
I'm left with a week to start my final exam,I need more information on chemistry...I don't know where to start
Same thought!
Let me tell you, It doesn’t change a fucking thing about college. Still sucks ass
I was waiting for you to start with the tour when you were talking about the book but it was definitely worth the wait! Thank You! =D
I laughed at that disappearing hand joke for 5 minutes straight lol
lol
Disappearing hennd
SAME AHAHAHAHHAHAHAHAHAHAA
Fascinating! I tutor an 8th grader in Science, and this is perfect for her. Thank you for the tip on the alkali metals in water videos, so awesome! She'll love that.
Thanks. Easy to understand explanation of the Table. Love the highlighter pen and photos.
Thank you! You're videos are helping me study for my nursing entrance exam! Much appreciated.
Thank you sooooo much I had a hard time understanding the periodic table. Will watch again and take notes before class starts!
Thank you Mr. Andersen for this youtube lesson! :)
Cool! this helps me remember all the things I forgot again!
You need to update this video to include the several elements near the end that have been discovered since you made this. I like the fact that you put Lutetium and Lawrencium in their correct places among the transition metals, however these two series are now called the Lanthanoids and Actinoids. Polonium is sometimes considered to be a post-transition metal, but I like it as a metalloid because it completes the stair-step pattern :)
Thank you very much Bozeman Science. Your videos are very helpful.
this was a lifesaver, thank you so much!
The Disappearing Spoon is one of the best books I have ever read, in my opinion. I love it!
I just finished reading "The Disapperaing Spoon." It is an excellent book. I am currently reading "The Violinist's Thumb." Sam Kean and Mr. Anderson should create textbooks together.
This was very helpful, thank you for that :)
Your so smart and kept my interest throughout the whole video!! You got my subscription thank you this helped for my final so much!!!
love your work
really helps a lot
BIG THX
N5 Chemistry in Scotland numbers the groups from 0 to 7 missing out the transition metals. Also, not all gallium is radioactive.
Gallium is NOT radioactive! In more detail: the naturally occurring gallium is composed of two isotopes, Ga-69 and Ga-71 - and both are stable.
Correct. Also far less toxic than mercury.
Gianmario Scott
my thoughts exactly! I'm actually watching this as a required assignment for chemistry class and I have gallium at home. Curious how this slipped by my teacher...
Darn it I was just about to say that.
My thoughts!
Thanks.Your keeping our science straight. Thanks
just ordered the book! so excited to read it!
you are so amazing! thanks a lot!! from korea
Excellent!
Thanks for your time to make such good education vedio. I use it teacher my son.
@ 0:52 I thought he was making a smiley face
same wtf
me too
same lol
me tooooooo
Awesome! Thanks a million !
We LOVE Mr. Andersen!!!!!!
Love his so informative - I learnt to much .
Excellent Excellent Excellent explanation....please keep it up and and upload similar stuff...
very well explained thank you
I always hated chemistry... It's intimidating like hell
Nice work, good communication skills.
Thank you for helping me with my Chem assignment!
This was very helpful thinks mr:Andersen
Thanks will be taking chemistry for the first time I never took this subject in high school so this is a need introduction to the periodic table.
thanks for this. helped me heaps
excellent video!
This is awesome!! Very helpful... Thank you :)
CAME TO STUDY, LEFT SUBSCRIBED
thank you very much!
Mr. Anderson, what video software are you using to create this video? btw love the video!
Świetny film
He seriously messed up the metals and non metals separation part
HI 4 years
@@br3ys3n16 lol.... but wha- like- i have a test today.... did he do something wrong?
@@zuzuderose1246 what grade are u in?
How
Damn it’s been 4 years since I commented this, and I don’t even remember doing it
great vid...clean and articulate!!
Great video I like it you make more sense than my teacher
Roses are red, violets are blue I came here to study, so did you
No I came here for the meme
I came to read your comment
Me too
I actually didn't I was just interested in it.
Thx! Very good!
Very helpful! Thanks.
amazing Sir
you teach very well
Thank you for doing this! I homeschool my kids and this helps out so much!
Nicoya_Beauty why?
You shouldn't they need a social life.
Sometimes if parents are smart or their kids get bullied they just homeschool them:) And they do make Homeschool co-ops, they're like one day a week private schools so that they DO socialize. And I know a homeschooler, and they are probably the smartest person I know... so good on you Nicoya!
"Galium is highly radioactive" are you sure about that
what video maker do you use! awesome vid btw! helped me a lot ... way better than most of periodic table vids ive watched =)
Thanks for making the table more regular to me by explaining that the last 2 rows should be a lot longer :D
Also why isn't [Al] a metalloid?
And finally are the 2 loose rows transition metals as well?
+sinekonata
Hello!
1.Aluminum(Al) is a metal since it's shiny, ductile and malleable.Also, it loses valence electrons(just like any metal), and is a solid at room temperature.
2.The last rows are called Lanthanides (1st row down) and Actinides (2nd row down).They are called "inner transitional metals".One reason they are separated from the rest is because they have an f orbital.To make the periodic table simpler and more organized ,they placed the elements in a way that the s,p,d and f orbitals elements are beside each other.
Wish that helped ;)
Gallium isn't radioactive. It has unstable isotopes, but all elements do. Some are naturally occurring, and others are produced synthetically (proton, neutron, or heavy ion capture). There are Plutonium-Gallium alloys, which are used in reactors though.
i love it
very good thankx
I have seen a number of videos handling gallium, so I think it is not normally radioactive
THANK YOU!!!
Thank you
I'm not learning this in chemistry yet but I like to learn more about what chemistry is about.
i liked the video just by seeing the thumbnail,later saw the video
good explaination about elements n their place in peroidic table
Thankyou... niga adipoly aanettaa
Thanks!
Thank you!! :)
excellent
Dang this helped me!
very nice tutor!!!
I came here to do late summer homework bc my mom is going to beat my ass if I fail and I have an 18 in science
felt that
Using this for homework
hiiii
can you tell me please what ddi you use to make this video what is that tool you use to appear on screen like a black board???
very good
THIS VID IS MORE USEFULL THAN MY TEACHER VID
on the transtion metal of group 2B is like that Zn are similar with group 1A
Science Homework is Lit
2:35 wait so 87 belongs on that group or not?
It does. Francium is the most reactive metal
Thanks. Try list-twist for the elements
very nice video thnks fr the help
Good one.
8 groups if you're talking about the specific groups like the transition metals, alkali metals etc. There are 18 'groups' or families, as in the columns. I guess he used them interchangeably.
And just like that we’ve gone across the whole universe
Question: where exactly are the lanthanides and actinides inserted into the periodic table? Is the order 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 5d1 4f14 5d9 6p6? So are they after the first column of the d block, or before the d block?
In the periodic table showing in the beginning, you have 15 elements in the f block. This isn't possible as there can only 14 f block elements. Why do some periodic tables show it this way?
use the numbers
very nice sir
No isolated compounds have been made, but certain ions and excimers have been detected. Therefore, they're not completely inert.
Can u explain what u mean by valance -and explain how lost and gain electrons
well that ended unexpectedly
Also, I believe that the noble gasses all have a filled outer electron shell, not 8 valence electrons, for helium has only a couple of electrons up to 4 and radon has a large outer shell capable of 18 or more, I would have to look it up.
Every atom has valence electrons, unless it has no electrons at all (such as ionized hydrogen). The definition of a valence electron is simply an electron that is capable of forming a covalent bond. Though the noble gases are not apt to do so under normal conditions, they can form bonds if their electrons are excited to a high enough energy level. Xenon is particularly easy to form bonds with in respect to the others.
can you do one about metals and non-metals
the number of valence electrons increases going from left to right so the noble gases have eight because the halogens before them have 7
that is quite interesting actually. my understanding of 'inert' in a chemistry context means an inability to chemically react, i.e. form covalent/ionic bonds with another element. When you ionise elements it doesnt mean they are chemically active, nor does the fact they can form excimers.
Where's the rest of the video? I want to learn
I believe that Gallium is not radioactive, but rather the Isotope Gallium 67 is. Regular metallic Gallium is considered non-toxic to the body, but Gallium salts can cause renal trouble.
But isn't valenselectrons just a name for the electrons located in the outer shell? Even if there are eight electrons in the outer shell, it's still eight valenselectrons, since the outer shell is also called the valens shell, right? I may be wrong though, haven't really read into this enough yet.
gallium is completely safe and readily available to the public. not radioactive whatsoever...
+Tim Miller Some isotopes of gallium are radioactive but the most common are stable. So go on play with it. :)
Electron configurations please make a video!
What software do you use to make these?
Thanks
What are elements Uun and Uuu? I know what Uub and Uuq are but what are the elements Uun and Uuu?
Do we need ALL of this for GCSE
