(A) Plutonium (A) Plutonium
(B) Germanium (B) Germanium
(C) Osmium (C) Osmium
(D) Cadmium (D) Cadmium
Answer: (A) Plutonium Answer: (A) Plutonium
Plutonium is the only radioactive element in the list.
Plutonium is a radioactive, silvery-gray, metallic element with the symbol Pu and atomic number 94. It has a high surface tension and viscosity compared to other metals, and tarnishes when exposed to air. Plutonium is created in a reactor when uranium atoms absorb neutrons, and is a by-product of nuclear power plants. It is the main fuel in fast neutron reactors, and more than one-third of the energy produced in most nuclear power plants comes from plutonium. Plutonium has five common isotopes, each with a different half-life, which is the time it takes to lose half of its radioactivityPlutonium is the only radioactive element in the list.
