This is possibly the best thing on the internet. I was so confused and had no idea how to write electron configurations and you literally explained it to me in under 10 minutes
I just wanted to say thank you so much for even existing!!! I have attempted to take college chemistry 4 times now (dropping every course) until now because it is my last class till I finally graduate. I went from hating this course to actually enjoying it because of you!!! You have made this fast paced class manageable and easy to understand. Please continue to make these videos!!! And again THANK YOU!
First year of university I fell asleep in class in the first row,my professor uses powerpoint and sits on the chair.Watching your videos i write down notes and re watch if I missed some info.
I've understood this lesson in just 7 minutes! Woah, smh for being excused in a week. when we got our test, I got like nothing because I don't understand. But thanks to this, I'll have a right answer on my final exam. thank you so much!
Thank you so very much!! Such a wonderful video..cleared all my doubts..I thought writing electronic configuration is quite difficult..but this video helped me to a great extent!!
I've taught biology and Human A&P for many years and now I'm teaching chemistry for the first time. I was confused about the number of valence electrons. I thought it was just the sum of the electrons found in the highest principal energy level(s). In the case of Mn, the 2 electrons in 4s shell would be the only valence electrons. Is this correct? In your video, you say that we would add the 2 electrons in the 4s orbital and the 5 electrons in the 3d for a total of 7. Thanks for your help.
I teach high school chemistry and I agree with you--valence electrons in this example would only be the outermost electrons, which are in the 4th energy level, or shell and don't include the d electrons. Only s and p electrons are ever valence electrons, d and f electrons will always have a lower energy level number in any given electron configuration that follows the Aufbau Principle.
Hi, I have a quick question: In your video, you state that the outer electrons are the electrons with the most energy levels, however, isn't 3d have a higher energy level than 4s since the electron wants to fill up the lower energy level first, in this case, 4s instead of 3d, which indicate that 3d has the higher energy level. So isn't the number of outer electrons being 5?
SOMEONE HELP ME i've got the question state the outer shell electron configuration of elements in group 15(5). Use n for the shell number. i know how to do all the other stuff like finding the electron configuration for an element but i just don't get this. I looked up the answer and it says it's ns2 np3 but i don't understand how u get 2 that. btw if u see this months ltr someone please answer cus this isn't hw im jus working thnxs
How would finding the valence electrons and outer electrons work for chromium and the other exceptions ? Since its an exception and doesn't fully fill the d orbital and technically has 6 valence?
What is the difference between outer and valence? I know that they are different but I want to put it into simpler words for my students since they are struggling. Pls help!
Depends, in the video, manganese is a transition element, so outer electron is found outer shell. Mn has 2 electrons. For valence electrons, Mn has 7 valence electrons. It is a transition element, it has 1 or more electrons. For representative elements, it has different rule.
Wait, cant you just take the outside electrons and minus it from the atomic number For example: fluorine's atomic number is 9 and its valence electrons is 7 and 9-7 is 2 If you use this method you also get 2
Outer electrons are the electrons in the highest energy level, while valence electrons are used for bonding two or more elements together. Valence electrons are also the electrons in the outermost shell of an atom.
So wouldn't the valence electrons and the outer electrons be the same thing being that the valence electrons also have the highest energy level?@@melissamaribel
They aren't the same number and they aren't the same overall. Valence electrons are in the outermost shell but are not found the same way as the outer electrons. You will later learn about lewis structures and how valence electrons are used for bonding so there is a major difference, you just haven't gotten to that section yet. Overall main difference is the use case of these different types of electrons. Outer electrons tell us the highest energy level of the atom and valence electrons tell us how many bonds are possible to be made with that atom.
How to find the electron configuration for the outer electrons for the following 1. K+ 2.ca²+ 3.cl- 4.s² 5.zn²+ Plz. Help...I'm really confused...I really need your help ...2morrow is our last day submission of our module...

You're very welcome!
This is the best explanation ever and high quality video
Thank you so much Claira!
@@melissamaribel
Yeah, now I completely understand this!
Thanks! 😊👍
Thank you so much! Just from watching 3 of your videos I understand the material my professor has been trying to explain to me. Thank you so much 💕

Finally someone who uses big words but then explains them simply, best video I have seen yet.d
You have taught me what my teacher couldn’t in two hours, in seven minutes. Thank you!
First year of university I fell asleep in class in the first row,my professor uses powerpoint and sits on the chair.Watching your videos i write down notes and re watch if I missed some info.
That's what I'm here for, no sleeping in my class 😂
you deserve so much more, you have helped me so much!!!!!!
Thank you 😊So happy to hear the videos are helping!
I watched the ad at the end of the video just so she can get the revenue her content is amazing.
THIS HELPED ME SO MUCH IN JUST A SMALL AMOUNT OF TIME
We spent 2 weeks on this stuff and I was so confused, literally have watched 3 of your videos and everything makes sense thank you so much.
Thanks so much!!!! This is the only video I found useful in UA-cam about valence electrons.
You teach better than the professor I'm actually paying lmao
Excellent and easy explained it!!! Thank You Melissa.

Wao thank you so much 😃 you should do more videos on chapter 6 and 7
Thanks but I don't know what chapters 6 and 7 are, they are different for each school.
@@melissamaribel loo
Lol
THANK YOU!!
thank youuu 😭😭
Thank you!
U are goddess of Chemistry!
Thank you so much ☺️
I am confused until now but everything is clarified
This was actually very helpful
What's the name of the jazz song in the background
So, why are you taking the previous noble gas and adding it to the configuration?

how about the element Te? As i wrote the electron configuration the last part is 5s2 4d10 5p4, but the valance electron of Te is not 16:(
Hi, I have a quick question:

Thank youuuuuuuuu very much
Q: determine how many valence electrons come from each subshell for P in PO4^3- polyatomic ion? Then, O in PO4^3-?
I get how to write the electron configuration , but the question says to indicate how many unpaired electrons each atom has. What does that mean?
SOMEONE HELP ME i've got the question state the outer shell electron configuration of elements in group 15(5). Use n for the shell number. i know how to do all the other stuff like finding the electron configuration for an element but i just don't get this. I looked up the answer and it says it's ns2 np3 but i don't understand how u get 2 that. btw if u see this months ltr someone please answer cus this isn't hw im jus working thnxs
How would finding the valence electrons and outer electrons work for chromium and the other exceptions ? Since its an exception and doesn't fully fill the d orbital and technically has 6 valence?
Thank you!!!!!!!!
what platform can i ask you some questions,,

how do you find the electron shells in an element? for this question Mn
Thank God for you

How about Uranium? Pls
Wait, cant you just take the outside electrons and minus it from the atomic number
For example:
fluorine's atomic number is 9 and its valence electrons is 7 and 9-7 is 2
If you use this method you also get 2

Plz. Help...I'm really confused...I really need your help ...2morrow is our last day submission of our module...
I'm one of ur followers and I'm really amaze on how you explain it it's very clear and fantastic it's help me a lot
I guess they are ions and isoelectron configs with noble gases.
Omg! ❤️❤️💋💋❤️❤️💋💋
W h a t
outer electrons of Mn should be 7.

man juh knees
waw so lit
😘
So confusing why did I take science as a course makes no sense
I don't understand lol
