Answer 2

Answer:

Unstable forms emit ionizing radiation and are radioactive. There are some elements with no stable form that are always radioactive, such as uranium. Elements that emit ionizing radiation are called radionuclides. When it decays, a radionuclide transforms into a different atom - a decay product.
