Thorium, radium, radon, polonium, thallium, etc.
Isotopes of lead (206Pb and 207Pb)
Lead (Pb) isotopes
Lead (stable isotopes)
Uranium hasn't stable isotopes.
Stable isotopes of lead.
Lead 206 or lead 207.
These are lead stable isotopes.
Uranium slowly decay to form the stable nucleus of Lead after a series of nuclear reactions.
Because the end products of uranium decays series are stable isotopes of lead.
Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.
The final product of the decay chain is the stable isotope 206Pb.
Decay series
Being radioactive, uranium is not a stable element.
Uranium slowly decay to form the stable nucleus of Lead after a series of nuclear reactions.
Usually called a 'decay chain', there is a series of radioactive decays which end with a stable isotope. Ex: uranium undergoes about 14 steps in the decay chain that ends with the formation of a stable isotope of Lead.
The decay chain in the uranium 238 series (also called radium series) id lead 206 (stable isotope).
Because the end products of uranium decays series are stable isotopes of lead.
Uranium hasn't stable isotopes.
The process of a radioactive decay is atomic nucleus of an unstable atom loses energy by emitting ionizing particles
The nucleus is too large to be stable. There is the theory of grouping of nucleons into alpha particles inside the nucleus and, through oscillations of the nucleus, one of these on one end of the nucleus can be repelled with a great enough force to push it out of the nucleus.
