1. Cesium-137 is a strong beta emitter. That means it                 becomes positively charged              &nb

1. Cesium-137 is a strong beta emitter. That means it

                becomes positively charged

                becomes negatively charged

                changes into a different element

                becomes a radioisotope of cesium

2. A radioisotope captures an electron. That means

                it emits a gamma particle

                it becomes a different element

                a neutron changes into a proton

                it emits a beta particle

    need help with this. thanks Please answer the following questions by replying: 1. Why is it that during alpha emission, the atomic number decreases by two, and the mass number decreases by four? In your answer you should consider what an alpha particle is. 2. In beta emission, the atom loses an electron, yet the atomic number increase by one and the mass number stays the same. How is this possible? It may help if you consider what happens to...
