Where is plutonium on the periodic table?
Plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons.
Is plutonium heavy element?
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized….

How much plutonium was used in the atomic bomb?
To begin with, the amounts of plutonium produced were invisible to the eye, but by August 1942 there was enough to see and weigh, albeit only 3 millionths of a gram. However, by 1945 the Americans had several kilograms, and enough plutonium to make three atomic bombs, one of which exploded over Nagasaki in August 1945.
Where did they get the element plutonium from?
Plutonium is a synthetic element and was produced and isolated in University of California, Berkeley. In 1940, Glenn T. Seasborg, Joseph W. Kennedy, Edwin McMillan and Arthur Wahl at Berkeley Radiation Laboratory, bombarded deuteron on an isotope of uranium in the 60-inch cyclotron, which created neptunium-238.
What’s the half life of a plutonium isotope?
U-239 has short half-life and it decays into Np-239 which then decays to form Pu-239. Plutonium isotope Pu-244 has a long half-life of approximately 80 million years even then it is believed that all primordial form of the element on earth has decayed forming other elements [2].
