<Uranium> emits them, you can see their mass to charge ratio under magnetic field and so deduce that they are <electrons>.

Caused by <weak interaction> TODO why/how.

The emitted electron kinetic energy is random from zero to a maximum value. The rest goes into a <neutrino>. This is how the neutrino was first discovered/observed indirectly. This is well illustrated in a <decay scheme> such as <image caesium-137 decay scheme>.
