decays
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
Beta
H+ ion
Polonium, which has an atomic number of 84, decays to astatine, which has an atomic number of 85, a negative beta particle is emitted.
It damages it. It can attack building materials such as metal and limestone.
Carbon-14 decays by beta-, which emits a W- boson that immediately decays into an electron and an electron anti-neutrino.
When a mineral spontaneously decays into subatomic particles, it has this property
dead
Waste that decays is called biodegradable waste. Dead plant material that has decayed (as in compost) is called humus.
After the internal organs have been removed the body decays
decays
Agrobacterium
unstable, radioactive
Curie: A unit of radioactivity equal to 3.7 � 10^10 Disintegrations (decays) per second.
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
