1. The problem statement, all variables and given/known data Use the periodic table to find the daughter nucleus after a gold nucleus (Au) undergoes beta decay. What would be the result if the gold nucleus had undergone alpha decay instead? 2. Relevant equations 3. The attempt at a solution Beta Decay: A=196.96655 Z=80 Au Alpha Decay: A=192 Z=77 Ir I have a couple of questions regarding radioactive decay....is it accurate to say that all beta decays for all radioactive elements results in the loss of a neutron and the gain of a proton? So, the element's atomic number increases by 1 but the mass number stays the same? Also, then is it accurate to say that all alpha decay for all elements results in 2 neutrons being loss and 2 protons being loss? So, all alpha decay results in another element different from the starting one? but beta stays the same element? Sorry for all the questions...I'm just not sure I get it. Thanks!
