This video is amazing!!!! Reading this topic from a textbook made it so confusing but thanks to you I now have a much much better understanding.

[@MSJChem]

Thanks, I'm glad that you found the video helpful.

[@shreyagupta7193]

Brother you are in which class

[@newtonsaha9406]

Thanks bro...to make the video clear understandable.I have searched many to understand the topics clearly but didn't. You have given all the answers what I had in mind in one video.

[@vasundarasur316]

Your videos are amazing . I am a new IB chem teacher and I cannot thank you enough for the clarity and the depth of knowledge you have . Thanks for posting them.

[@MSJChem]

It's comments like this that make all the time and effort worthwhile, thanks!

your explanations are short and precise, really helped to break down the confusing parts of my chemistry textbook, thank you!:)

[@MSJChem]

Glad I could help.

[@BigDaddyGuagg]

thank so much for your videos, will be a great resource to go over before my chem tests :)

[@brianyaw1215]

Thanks a lot , you just saved my time of reading 5 pages of the textbook which can take more than 5minutes of understanding

[@laugiuliani7606]

Mike, I've got a question. An electron from one of the low energy d orbitals absorves a certain energy, a certain color, that males it "jump" to one of the high energy d orbitals. Now, what happens later on? Does the electron keep in that exited state, or does it jump down back to the low energy d orbitals, librating the same energy, the same color, it had taken before?

[@MSJChem]

When an electron transitions back down to a lower d orbital it will emit the same amount of energy that it absorbed in the first place.

[@laugiuliani7606]

Mike, thank you for answering. So, you sad that we see the colors that a complex ion reflects. But, according to your answer, shoudn't we also see the foton that the high energy electron emits when it jumps back to a low energy orbital?

[@vinayseth1114]

One question though-why doesn't the light stop being emitted? What makes it get emitted perpetually?

[@MSJChem]

As long as light is being absorbed, it will be transmitted. In other words, there must be light present for a solution of complex ions to be coloured.

[@Alexa3077]

Sir, what happens to the electron that is excited ? How does it return to the ground state?

[@MSJChem]

By emitting the energy that it absorbed in the first place.

[@Alexa3077]

@@MSJChem does it emit the same energy that it absorbed? And does it emit in the form of light? If so, wouldnt the color of that compound become white since it is emitting or reflecting all of the colors?

[@MSJChem]

It will emit the same energy that it absorbed when it returns to the ground state (n=1). The energy emitted can be in the form of UV, visible light or IR. The hydrogen visible emission spectrum shows 4 different colours depending on the level to which the electrons transition to.

[@emilioestrada1860]

How is complementary colour transmitted?

[@MSJChem]

When light passes through a solution, certain wavelengths are absorbed and certain wavelengths are transmitted (pass through the solution). The wavelengths of light that are transmitted correspond to the complementary colour of the wavelengths of light that are absorbed.
