Electronic Configuration
Are you finding electronic configuration confusing? This video simplifies everything you need to know! Learn how electrons are arranged in atoms, understand energy levels and sublevels, and master the Aufbau principle, Hund's rule, and Pauli exclusion principle.
We'll walk through step-by-step examples for elements like hydrogen, oxygen, sodium, and more. Plus, you\u2019ll learn how to use noble gas notation to make writing configurations easier.
What you'll learn:
✅ What is electronic configuration?
✅ How to fill orbitals using the Aufbau sequence
✅ The rules for electron arrangement (Pauli exclusion, Hund's rule)
✅ Writing configurations for different elements
✅ Common mistakes to avoid

Love this.
Glad to hear that 😊
This is so detailed I love it
Glad to hear that 😊
Exactly what is on my note thanks
Happy to help
Thanks a lot that was helpful
You're welcome
@@lrntube8 That calcium chloride does the 2 mean the number of atoms that is there or that is present there
@JoshuaKelvin-j4l it represents the number of atoms of chlorine that combines with calcium.
@@lrntube8 Ohhh OK MA thank you ma
Thanks😊
Welcome 😊
Hello ma i did my jamb regularization last month and jamb have congratulated me and i accept the admission on Caps but when i went back to check admission status it showing unauthorized access
Hello, sorry to hear about that. Have you paid for admission letter and Result afresh?
Thaaaaanks ❤
Glad I could help
I am so impressed with the concise and simple explanation.
Glad to hear that.
Mine is showing that I'm not on the matriculation list please why is that?
It may be due to one of the following: 1.You haven't paid for your jamb result or admission letter 2.You didn't accept admission on jamb caps (supplementary admission) If you have already done number 1 and 2 then you may have to do Regularization.
@@lrntube8 Thank you,I have accepted and paid for my Jamb admission today I'm now on the matriculation list
@madakiphilomina03 Glad I could help.
Mine is saying I didn't register for the exam.... please why
Are you sure you're using the correct jamb registration number.
@@lrntube8 Yes ma
Create a ticket on www.jamb.gov.ng/support. Explain your complaint.
❤❤❤
Thank you
Excellent
Glad I could help
Calcium Chloride = Ca + C12 🤔 You're an amazing teacher.❤
Thank you. Glad I could help

Thanks so much This is as really helpful
Glad I could help
So educative for science students
Yea good video
Wow, This is very helpful,it has helped me to eat well
Hello, I couldn't find my name on the matriculation list , I think it's due to registering with same email, so it's bringing the last course I registered with..
Try using the correct reg. Number
Good job
I can't input my registration number, its not working

It's ok🤗
I liked the video. Very educational😁
Thank you.
You're welcome!
Kudos . But please I thought Arthropods come before mollusca in evolutionary trend. Please help
Thanks for well explained
@5:25 glutamate is excitatory. So how does lack of it cause insomnia. Gaba is inhibitory.
@@lrntube8 You also state low Gaba is related to bipolar. You are the first I've heard say that. Bipolar has always been tied to dopamine/seratonan. Please cite references to glutamate directly effecting sleep, and Gaba cause for bipolar.
I was reading the comments, so I thought I'll share what I found! It's not a recent discovery, but it was discussed as a theory in 1995.

Good job done
Centromeres begin at 1:41. That's what I came here for, thanks for the visual!
I can undestand clearly
Your voice does not sound clear. Something wrong with your mic
Try using an earpiece

Your lecture is good and you do very nice ppt. Can you give me your lecture? I make materials for teaching.
how do i know if my second choice institution has offered me admission on my jamb portal
That's a great question but I'm not sure how at the moment.
I liked it, but why did you put a white hand on the writing edit bro
💯💯
This lacture is helpful for me.thanks.
Nice
