Unstable and decay radioactively
WebRadioactive decay isn't combustion or fission. Depending on the amount and type of radioactive material you might get sick, but it's not going to take down the building. Lead (Pb), Cadmium (Cd), Arsenic (As), Thallium (Tl), and mercury (Hg) are all deadly poisons. Actually, consuming elemental mercury is pretty safe. WebNuclear Isochrons. Some chemical elements have isotopes that are inherently unstable and undergo radioactive decay. (Isotopes of the same element always have the same number of charged protons in each atomic nucleus, but have different numbers of noncharged neutrons. Isotopes of a single element act the same chemically, but often behave ...
