WebAlpha decays are common in very heavy nuclei. Although nuclei and other particles can change (e.g. beta decay of a neutron) the reactions must satisfy 3 conservation laws. … WebAnswer and Explanation: 1. When carbon-10 undergoes nuclear decay, it engages in electron capture. If we classify electron capture as a type of beta decay, then we can discuss what happens when it undergoes beta decay. In electron capture, the weak nuclear force causes the nucleus to absorb an electron. This initiates a process that transforms ...
