AI Thread Summary
To predict the electrical potential and current on a copper plate from a beta-emitting radioactive substance, one can calculate the average number of electrons emitted per second using the decay constant and the number of radioactive atoms in the sample. The decay constant is derived from the half-life of the substance. Factors such as the radiation level, plate geometry, and substance density can influence the overall calculations, allowing for estimations of the electrical effects on the plate due to the emitted electrons.

Hello. Say that I were to take a beta emitting radioactive substance, crush it up, and apply it to a copper plate. Is there a way for me to predict the electrical potential and/or current on the plate (due to the emitted electrons) based on known data, such as radiation level of the substance, plate geometry, substance density, etc?

You can calculate the average number of electrons released per second from the equation:
dN/dT=-xN
x= decay constant=0.693/half life,N= number of radioactive atoms present in your sample.
 

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!!
