Nobelium is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes.
Berkelium is a transuranic radioactive chemical element with the symbol Bk and atomic number 97. It is a member of the actinide and transuranium element series.
Seaborgium is a synthetic chemical element with the symbol Sg and atomic number 106. It is named after the American nuclear chemist Glenn T. Seaborg.
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air.
Technetium is a chemical element with the symbol Tc and atomic number 43. It is the lightest element whose isotopes are all radioactive, none of which is stable other than the fully ionized state of ⁹⁷Tc.
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.
Rutherfordium is a synthetic chemical element with the symbol Rf and atomic number 104, named after New Zealand physicist Ernest Rutherford.As a synthetic element, it is not found in nature and can only be created in a laboratory.
Moscovium is a synthetic chemical element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia.
Oganesson is a synthetic chemical element with the symbol Og and atomic number 118. It was first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow, Russia, by a joint team of Russian and American scientists.
The world's nuclear power plants have generated an estimated 300,000 tons of high-level radioactive waste that must be safely stored for 100,000 years or more. Every year, they generate another 12,000 metric tons of high-level waste. Takes viewers deep into the Onkalo facility as it is being constructed and asks Onkalo representatives, scientists, theologians and others to address fundamental but challenging questions.
Investigates some of the key concepts of physics. Using a drum kit, we look at how sound works, how we make it, and how it gets around. Also, examines electricity and electromagnetism and notes the similarities between a remote control car and a mobile phone charger. Finally, takes a look at radioactivity and identifies a radioactive device that can be found in almost every family home.
Carbon (from Latin: carbo "coal") is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group 14), which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent - making four electrons available to form covalent chemical bonds. Three isotopes occur naturally, 12C and 13C being stable while 14C is radioactive, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.
A mutagen is any agent (physical, chemical, or biological) capable of altering the structure of DNA within human cells. This program explores how some mutations are a natural process resulting from errors in the copying and repair of DNA and how some mutagens naturally exist in the world (e.g., UV radiation, cosmic rays, and some radioactive isotopes). Others are specific chemicals that have been synthesized for use in manufacturing or other industries. Mutagens may also arise during the metabolism of certain foods. In many cases mutagens may also lead to the development of cancers.
