Manganese: The Element That Lied to Us?🧲

Thank you so much really trying the best :)

@@CubeChemistry - You asked for feedback. Here it is: Your phrasing in general, and pronunciation of certain words in particular, was disconcerting and distracting. Example: with CObalt, which you pronounced as co-BALT, sounding almost like 2 distinct words. That causes my brain to do a sort of Reset, and a few of your words may go by while the reset completes. I've only ever heard similar vocal patterns from a character on TV, and his manner of speaking may have been an _actor's affectation._ I assume yours is real, and due to your geographic origins. Where might those be?

[@CubeChemistry]

@@YodaWhat First of all thanks for the feedback. Now that you mention it yes the pronunciation of for instance Cobalt comes indeed from where I live. I try to the best of my ability to use the correct pronunciation but yes in this case I used the one from the Netherlands where in Cobalt the emphasis sis on the first part of the word. In English as you are pointing out correctly this is on the second part of the word. I started this channel as a fun way to just collect the periodic table and tell some fun facts about the elements. But since the channel is now gaining quite an audience I need to do better. I will keep putting more in it to make sure the pronunciation will be better as well as the video's :) Again thanks for the feedback!

Mn is one of the most prolific activators of fluorescence in fluorescent minerals. The famous Sterling Mine in New Jersey with the largest concentration of fluorescent minerals anywhere in the known world owes the overwhelming majority of its main fluorescent species' (willemite, clinohedrite, calcite, hardystonite, esperite...) luminescence to manganese impurities. The color of fluorescence spans the entire visible spectrum and is a function of the host crystal lattice shifting the emission peak. In antique glass where it was heavily used as a fining agent and clarifier, the glass will fluoresce green under pure 365nm longwave UV, and phosphoresce for a fraction of a second in the orange.

[@CubeChemistry]

@@Muonium1 thank you so much for that insight!

[@spvillano]

Didn't know about the brief phosphorescence. Of course, Google's improved their searches so much, phosphorescence is fluorescence in their results, making their engine about as useful as a bustline on a bull... Pity, was curious as to the wavelengths emitted.

[@Muonium1]

@@spvillano The fluorescence peak is around 525-535nm and depends on the glass piece. I've tried to capture the phosphorescence but it's too weak and brief to get good data. All I can say is it's orange. You can observe it for yourself with any quality filtered 365nm light at an antique store.

What in the world are you doing : that this data is at hand ? ...xray spectrometer crossed with a Geiger counter?

[@Muonium1]

@@Thom4ES I collect fluorescent minerals and glass. UV-Visible spectrometer and a longwave / shortwave lamp.

[@KwK-c7t]

👍 I like seeing other people admit this channel is underrated. The triangle base for your cubes deserves an update ;) Like the last time, bedankt voor je werk 😊

[@CubeChemistry]

@@KwK-c7t yeah it fun to see all responses!! So the triangle base is actually not what it seems. It is a base to actually hold a cube. Not a cube like this though but a Rubix cube. We decided to put some cardboard over it to hide that fact. In the next episode we may try some new ideas around this. Thanks for the feedback!!

[@EgonSorensen]

Yup, also thanks for his work from Denmark :ø) Edit - Just checked out the other videos on this channel, wow.... What a good resource... Subscribed immediately

I am so glad your channel showed up for me. KZbin does a really bad job at suggesting a new channel 😬, but not this time👍I appreciate you explaining it so clearly, even I can follow..lol..so many channels in this space seem geared to those who already have the educate needed to understand. Thank you 👍👌 😎 cat

Yes indeed!

This seems to be very good. Thank you :)

[@rursus8354]

Nope, the name "Manganese" does not derive from "magnetic stone". Like Magnesium and magnet it derives from the location of Magnetes an ancient Greek tribe, and that place was the Magnesia Prefecture. Some stones there were magnetic, some others were not.

[@CubeChemistry]

Thank you for the feedback!! I think the literal text was: the name manganese was derived from the word Magnes. And that is right but you are right that Magnes can be derived from the place where it comes from where some stones had magnetic properties. So yeah i could have been more specific there…

[@TomLaios]

How on earth is it possible to count individual electrons?

[@CubeChemistry]

This is really a good question!! And we cannot. Well at least to my knowledge. But to make these episodes understandable this is how we explain it. For instance for an electron it is impossible to determine the speed and the place where an electron is at the same time. But this brings us into the realm of quantum mechanics which is kinda outside the scope of the video’s. So let me give a hopefully somewhat satisfying answer: in chemistry we study the behavior of elements this behavior is studied is extremely close detail and when you look at the physics of small particles chemist and physicists can explain by using examples that i used in this video.

[@JimmyMatis-h9y]

you can manage it's position and velocity at the same time but without perfect accuracy. the more precisely you can locate it, the less precisely you can determine it's momentum and vice versa.

[@JimmyMatis-h9y]

Metabilism, organism, metabilism, great teacher bad pronunciation......

[@ericastier1646]

You speech explosive articulation gets in the way when you explain difficult concepts. Your examples are not very good and the diagrams not good. Overall i question if it is worth for me to spend the time listening to you. Making a lecture is a professional occupation and this is amateurish. Not bad but not very good.
