Thank you so, so, so much!

Good leson
Thank you
This is wrong electronics configuration
👍🏽
Thanks for sharing
You are welcome.
found this helpful
Awesome, thank you.
So i got a question on a test saying put down the number of valence eletrons of this element, and i put 3. But she marked it wrong becuase she said you have to look at the configuration. And that the answer was 2. But the question did not ask "how many electrons are on the outer shell" and instead said "how many valence electrons are there". Would the answer for be 2 or 3?
Looking at 2, 8, 9, 2 there are 2 valence electrons. Remember when they say valence electrons, always account for the elections on the valence shell (last shell).
thank you so much, I've been looking for an easy explanation and it's so helpful for my reporting!
You are welcome.
At the start bro really said 🤨🤨🤨
😉
Thanks so much. I had chemistry homework on this but we hadn't even learnt about it in class yet. I had to search online for the answers and came across this video, which was straightforward and did the job. 👍
Happy it was helpful

Why must there be a reaction force up the pivot, and not opposite of where the weight of the plank is?
Consider upwards and downwards forces.

I am doing cxc for 2025. And I am scared my teacher is gone overseas and the new teacher that we got doesn’t have any experience and I don’t understand when she teaches😢
Do your best preparing and it will happen.
@mr knight do you do Social Studies?
Sorry, I do not.
Good job sir
Thank you.
My science teacher put this on for us today <3 Nice work!
Awesome, thank you for watching.
Awesome, I love the video. Next time, no music. I had a hard time listening to you.
Thank you, sorry about that. There is a link for a version without music in the description.

Hello Mr Knight will you be doing any zoom classes? Or only on youtube?
Mainly on, but I will see.
I'm entering 10th grade and I'm planning to finish this, do some work and a few papers before I start the 4th form year! I may not be too close to doing the exams but I'm excited and I really want to get ahead! I'm doing CXC next year, Mathematics and English, Thank you Mr. Knight!
Awesome and best of luck. Keep tuning in.

You are welcome. I am happy to hear.
Good Morning Mr. Knight I would like to thank you for your aid in me and my twin brother in obtaining a 1 in Physics and Biology. Thank you for providing simple and easy to understand videos on extensive topics that proved to be arduous. May God bless you and your family 🙏.
You are most welcome and congrats on your achievement. I am happy to hear such news.
Hello, do you have the link for these past papers?

Thank you
Why 3 d 6 can be written before 4 s 2 . What is the reason?
3 and 4 represent the shells. The 3rd shell is theoretically filled before the 4th.
@@science_exam so whenever we write the configuration we should right in the spdf order? ex: 3s2 3p6 3d10 3f14 ....
Fanums tax?
?
@@science_exam ok
