Through the weak nuclear force, one quark flavor can transmute into another. However, current data and theory indicate that ...

Note that the mass numbers and atomic numbers are equal (i.e. they balance) on both sides of the equation. An unstable nucleus can emit a fast-moving electron called a beta (β) particle ...

In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as ...

When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into polonium.
