True or false uranium-238's stable form is lead
1 answer:
True
Explanation:
Lead is the stable form of uranium 238. Lead-206 is a product of radioactive decay of unstable uranium 238 isotope.
- Atomic nucleus have a specific neutron/proton ratio that ensures their stability.
- Nucleus whose proton/neutron ratio is different from that of its stability ratio will be unstable and split into other nuclei.
- This splitting is accompanied with emission of small particles of matter and or electromagnetic radiation.
- Unstable uranium -238 undergoes 14 radioactive decays to produce a stable form which is Pb-206
