Chemistry Unit 5: Transition Metals
By the end of this video, you should know that transition metal characteristics from Ti-Cu come from an incomplete d sub-level in atoms or ions, and that these characteristics include complex…

Thank you! Your voice is very agreeable and you were able to break the
topic down in such a way that it was easy to absorb! This was excellent!
life saver
Very good! This is very helpful- thanks.
bro, guys..one thing…the colour is actually what wavelength is absorbed.
the emission of colour does not happen like in flame test. right? its like
the colour is what has been absorbed by the transition..the electron
falling back doesnt give colour AT LEAST here..(in the case of transition
elements)
Thanks for this 😀 youre easy to listen to. Im gonna check out your ligands
video too.
V5+, Cr6+ and Mn7+ aren’t coloured ions on their own – with the example of
Mn7+, it’s only when bonded as MnO4- etc and it promotes electrons from the
oxygen into the Mn d-orbital. This absorbs yellow light and transmits the
purple colour 🙂
I love you, if I ever meet you in real life, I’d give you a hug!
Then, how come V5+, Cr6+ and Mn7+ still make colour even though their
d-orbitals are empty? I can’t find this answer anywhere and it’s really
confusing. Brilliant video though, we just started transition metals. I
sure look forward to learning all the colours! -_-
actually λ = c/f
Brilliant! super helpful thankyou so much 😀
broad “complex” topic, what a pun! 😀
thank you very much, could you do more on unit 5 please >.<
Very clear explaining & clear voice, I enjoyed studying from this video –
Thanks so much Mr Jake
Dear Jake The wavelength symbol is the Greek letter lambda, λ, measured in
metres (SI) but often in nm, as you rightly said. I did A level physics,
and we were taught that f is the symbol for frequency, and yes, you rightly
said that wavelength, λ = 1/f. Your video was very helpful (I have my exam
tomorrow), so good job.
thats only for E.M waves?
Great video, but Plank’s constant should have the unit Js not J. 🙂
