May not even be the right forum...

Post by dottydot » Tue Oct 17, 2006 3:00 am

I am SO confused. So confused that I am not sure if this is in the right forum or not. The question is:

Which of the following is not a way that a molecule releases energy gained by absorption of a photon?

a. fluorescence
b. nuclear decay
c. loss of an electron
d. light
e. heat

I have ruled out everything except b and c and now I am STUCK. If anyone has an explanation that would be wonderful. Thank you.

So it would be "c"? Loss of an electron?

I looked it up, I still don't understand. I guess I don't know what nuclear decay would mean. Is that what would happen after a nuclear reaction? Everywhere I look they talk about alpha, beta and gamma decay (none of which are discussed in my study materials, only online); I don't know what any of these mean or how they are relate.

Now I don't think it is C, I think it may be B. I turned in the assignment with C, but I think that is wrong.

photoelectric effect is loss of an electron due to energy from photon so C is a way of losing energy....you can't cause nuclear reactions by shooting it with photons

Fooey. I really didn't understand that...obviously.

Thank you for your explanation.
