Madame Curie - Marie Curie and Radioactive Elements History & Culture. Dr. Marie Curie is known to the world as the scientist who discovered radioactive metals such as radium and polonium. Curie was a Polish physicist and chemist who lived between 1867-1934. She was born Maria Sklodowski in Warsaw, Poland, the youngest of five children. When she was born, Poland was controlled by Russia.

Gold: the essentials Gold: the essentials. Most metals are metallic grey or silvery white whereas gold is characteristically a metallic yellow colour, in other words gold-coloured. Caesium is also gold coloured. The gold colour seems related to relativistic effects of the outermost gold orbitals.

- Well, to be quite honest I'm not sure myself. I know the rarest retired PET items though. Those would be the brown Cheeky Dog item, the B&W Cheeky Dog Stove, the Love Puppy couch, and the Cheeky Cat item, as far as I know.rancium is the rarest metal. It is estimated that only 30 grams of it exist in earth's crust. However, most of the artificially created elements on the periodic table near th … e end are equally rare because they only exist for extremely small amounts of time and so they do not exist anywhere in the universe currently.

Curium Element Facts Curium was the third synthetic transuranium element of the actinide series to be discovered. It was discovered by Glenn T. Seaborg, Ralph A.James, and Albert Ghiorso in 1944. Curium-242 (half-life 162.8 days) was produced by bombarding plutonium-239 with alpha particles in the Berkeley, California, 60-inch cyclotron.ource: Curium does not exist in nature. It is a synthetic element and it is produced in nuclear reactors by bombarding plutonium with neutrons. Isotopes: Curium has 15 isotopes whose half-lives are known, with mass numbers 238 to 252. Curium has no naturally occurring isotopes.

Definitions &Translations Mu-metal Mu-metal is a range of nickel-iron alloys that are notable for their high magnetic permeability, composed of approximately 77% nickel, 16% iron, 5% copper and 2% chromium or molybdenum. The high permeability makes mu-metal useful for shielding against static or low-frequency magnetic fields.

- When a uranium atom decays, one of the products is radium. Radium also decays, and after a series of decaying events, eventually becomes lead. Radium, then, is always in a state of slow metamorphosis, and during this time it continually discharges electromagnetic rays. This is why it’s profoundly foolish to carry radium around in your pocket – but Curie and other prominent physicists were just learning this.

Cerium Cerium is a chemical element with symbol Ce and atomic number 58. It is a soft, silvery, ductile metal which easily oxidizes in air. Cerium was named after the dwarf planet Ceres (itself named after the Roman goddess of agriculture). Cerium is the most abundant of the rare earth elements, making up about 0.0046% of the Earth's crust by weight. It is found in a number of minerals, the most important being monazite and bastnaesite. bastnäsite

- Available online 1 May 2003. The limited fabrication possibilities will be decisive in the design of curium fuels and targets. It appears that there are significant advantages to be gained by separating the Am and Cm at the reprocessing stage, simply to concentrate the problems caused by Cm and limit its mass flow.
