The atoms of some elements can be made
radioactive by
1)placing them in a magnetic field
2)bombarding them with high-energy
particles
3)separating them into their isotopes
4)heating them to a high temperature
The atoms of some elements can be made radioactive by: bombarding them with highenergyparticles: Choice 3.
Definition:
Radioactivity is a process, (spontaneous) by which the nucleus of an unstable atom loses energy by emitting radiation which may include alpha particles, beta particles, gamma rays and conversion electrons, otherwise known as highenergy electrons.
However,radioactivity is observed as a natural occurring process, the phenomenon can also be artificiallyinduced typically via the bombarding atoms of a specific element by radiatingparticles, thus creating new atoms.
