Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
The half life (not life span) of the most important isotope of plutonium (239Pu) is 2,41.104 years; for other isotopes see a table of isotopes.
The half life of 239 Pu is 24 200 years.
Plutonium is considered a very toxic element; it accumulates in the body without being easily metabolized or eliminated, doses as low as 5,000 total particles can be enough to increase the risk of cancer, and its half-life of 87 years is a good match for an average human lifetime. The halflife of Plutonium-239 is not 87 years, it is 24,200 years. I cannot find any isotope of plutonium with a halflife near 87 years, so I don't know where that came from.
It is used to determin the age of different organic materials, by measuring the amount of carbon-14 in a material, compared to the amount of carbon-12.

Nuclear energy as used in power plants results from fission of uranium235 and plutonium239
Yes.
From the fissioning of the nuclei of uranium235 and plutonium239. The energy released appears as thermal energy in the surrounding fuel material
yes
U-238 --> alpha + gamma + Th-234, halflife 4.51E9 yearsTh-234 --> beta- + gamma + Pa-234, halflife 24.10 daysPa-234 --> beta- + gamma + U-234, halflife 6.66 hours
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
Nuclear energy is energy released either by fissioning of heavy nuclei such as Uranium235 or Plutonium239, or by fusion of light isotopes such as those of hydrogen.
To make a nuclear bomb, you need the fissionable material such as a Plutonium239 isotope, an explosive to start the nuclear chain reaction, a detonator, and a pusher.
The half-life of carbon-11 is 20.334 minutes.
