AI Thread Summary
Every object displays a specific color due to its ability to reflect certain wavelengths of light while absorbing others. This phenomenon is primarily governed by the behavior of electrons within the material, which can only interact with specific frequencies of incoming light. When light hits an object, electrons may absorb energy at certain frequencies, leading to the re-emission of light or the transfer of energy to the surrounding material. While this explanation simplifies the complex interactions involved, it captures the essence of how color perception occurs at the quantum level, highlighting the significance of electron energy levels in determining an object's color. Understanding these principles requires a foundational knowledge of quantum mechanics and electron behavior.

Hello friends,

Every object has certain color, because it reflects that potion of light & absorbs all other visible radiation,

What is the mechanism that happens on the surface of a body, which makes it reflect certain portion & absorb rest portion.

How much do you know about quantum mechanics and electron energy levels?

The basic idea: electrons in the material cannot react to all incoming light, just some frequency ("color") ranges. In those ranges, they can absorb and re-emit light, or absorb light and release the gained energy to the surrounding material.
That is not a perfect description, and not all processes follow that pattern, but it should give some idea what happens.

I have fair knowledge about electron energy level & quantum mechanics,

can you please guide me to understand this phenomenon.

Thank you.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
