Kindergarten Number Sense Worksheets. Music Meets Math Worksheets 1-2 - Students will color one-five instruments in a set and practice printing the names of the instruments. This worksheet reinforces instrument recognition, counting to five, vocabulary, and handwriting.
Plutonium (IPA: /ËpluËËtÉÊniÉm/) is a radioactive, metallic chemical element. It has the symbol Pu and the atomic number 94. It is the element used in most modern nuclear weapons. The most significant isotope of plutonium is 239Pu, with a half-life of 24,100 years. It can be made from natural uranium and is fissile.
Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs.Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.Plutonium predominantly emits alpha particles â a type of radiation that is easily stopped and has a short range. It also emits neutrons, beta particles and gamma rays.lutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
