Tp persue an old pasttime of mine, does anyone know a site that has halflives of all the elements and the elements they split into? I used to be a serial halflife calculator :)

I was going to say, just use Linux/Kalzium, but I looked, and is this the sort of thing you wanted:

Code:
Al  Block: p
icon  Electronic configuration: 1s2 2s2 2p6 3s2 3p1
icon  Density: 2.7 g/cm3
icon  Covalent Radius: 118 pm
icon  Ionic Radius (Charge): 53 pm (+3)
icon  Atomic Radius: 125 pm
icon  Mass: 26.9815 u
icon  Isotope-Table
  Mass  Neutrons  Percentage  Half-life period  Energy and Mode of Decay  Spin and Parity  Magnetic Moment
  25.9869 u  13  740000 years  4.003 MeV β+(82%) EC(18%)  5+
  26.9815 u  14  100%  5/2+  +3.641504 μn

(I didn't realise that Aluminium had a radioactive iotope! Mind you, with a half-life of 3/4 million years, it's not very radioactive.)
