Phosphor Powder for solar cells

AI Thread Summary
Phosphor powders do not emit electrons when struck by light; instead, they emit photons after being excited by other photons within specific light bands. The discussion also touches on the idea of using phosphor powder in solar cells to generate electrons, but this concept is clarified as impractical since phosphors primarily function by emitting light rather than generating electrical charge.

'Does a phosphor powder give off a photon or electron when struck by light?'

I was just thinking maybe a solar cell made of phosphor powder to emit electrons.

I failed chemistry at uni so yea =/, the answer might be obvious but i'd have no idea.

No, phosphors do not give off electrons when struck by light. However, phosphors do emit photons after being struck by other photons (within certain bands of light).
 

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!!
