      Step 1: 1.442 MeV, Step 2: 5.49 MeV, Step 3: 12.86 MeV. Steps 1 and 2 happen twice for every one Step 3. So the total is 26 MeV. MeV means million electon volts. Most chemical reaction only give you a few electron volts, so this is extremely energetic.

      @@almoni127 The weak force has a similar pattern to the other forces. What's actually happening is an exchange of W-, W+, or a Z bosons. In fact, the weak force and the electromagnetic force have been unified into something called the electroweak interaction. I don't fully understand the details, but there's unified model that describes both forces. The reason the weak force is so weak is because the W-, W+, and Z bosons are pretty massive and thus harder to produce.
