what is radioactivity and radioactive elements? give 4 example of radioactive elements
Answers
Answer:
An example of a radioactive chain is uranium-238. As it decays, it transforms through a number of elements including thorium, radium, francium, radon, polonium, and bismuth. It finally ends up as a stable isotope as the element lead.
Radioactivity is a process in which particles decay to become stable .It is also known as Radioactive Decay.
Radioactive elements mean the elements that are not stable due to which they give off their radiation to become more stable.
Examples-radium,radon,polonium,
uranium,etc
If you are interested in knowing the types of radioactive decay,then you can watch the video as the concept is understood better when you go in detail
Type BRAIN MOSAIC on YouTube search bar and see one of the radioactive videos in the list....hope you find it informative.
