To all those chemists (or wanna bes) out there


Recommended Posts

I have a report due tomorrow on Thallium 201 and there is this on section in the report on equations so after doign some research I found out that thallium 201 is a result of Lead 201 being decayed

so I started to write out my equation

.201............201

......Pb..-->.......Tl + ??

...82..............81

something that a atomic mass of 1 and a mass number of 0 .. can someone explain this decay mode to me

cant be a apha or beta decay.. Iam guessing it is a positron decay. it is possible for someone to tell me a little more about it I researched on the web.. and I am lost..
