Question
Let us first consider the three different forms of radiation. Alpha Decay: Alpha decay is the emission of a helium nucleus (2protons and 2 neutrons) from the nuclei of the unstable atom. It loses energy by decreasing the number of protons and neutrons of the parent nuclei. a. What properties would you expect of an alpha particle? Remember that this particle is positively charged. b. How would this Alpha particle likely interact with the surrounding matter? Answer this using information you have learned about charged particles. Daughter nuclei A daughter nuclei is the nuclei that remains after nuclear decay has occurred. Parent Nuclei A parent nuclei is the original unstable nuclei that exists before radioactive decay occurs.Explanation / Answer
a)
An alpha particle can be referred as helium nucleus,
Charge =3.2*10^-19 coloumbs
mass of alpha particle =4 amu
b)
Alpha paricle being positively charged creates an electric field around it directing away from it.
E =kq/r^2, q =3.2*10^-19
