Title: radioactive decay
Post by: nevada on Dec 8, 2013
In each of the following radioactive decay processes, supply
the missing particle.

73^Ga--> 73Ge +?

i don't know how to do this question , i don't really understand it, like i know how to do the one with the proton given but not this,

can you please explain the steps to do this,

Look at these examples

In each of the following radioactive decay processes, supply the missing particle
a.  60Co → 60Ni + ___
b.  97Tc + ___ → 97Mo
c.  99Tc → 99Ru + ___
d.  239Pu → 235U + ___

Answers:

a.  b (beta, not a b)
b.  b (beta, not a b)
c.  b (beta, not a b)
d.  a (alpha, not an a)

Hi nevada,

You can find the number of proton by looking for those elements in the periodic table (Ga has 31 protons, and Ge has 32).
This looks like Beta- decay, where one of the neutron is converted to a proton and emits an electron is the process.
7331Ga   ---->   7331Ge + e

Hope this helps,
Laser

I'm just going to leave the chemistry questions alone lol I suck at them.

ok so just to make sure i am doing this correct


192^Pt ---> 188^Os +?

i found Pt =78 and Os=76

i got 2e?
 is that correct?

thanks !
