Cesium-133
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Barium is the heaviest non-radioactive alkali Earth metal, with an atomic number of 56.
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
fluorine is the most reactive non metal in the periodic table.
Hassium is a synthetic element that is a metal. It is highly radioactive and has no known biological functions.
non radioactive element
No, it is not a metalloid. Plutonium is a metal, as are the other elements in the actinide series.
Fluorine is the most reactive non-metal.
Bohrium is a synthetic element that is classified as a transition metal. It is radioactive and has only been produced in small quantities for scientific research purposes.
A radioactive material is radioactive. Period. The atoms of radioactive material have unstable nuclei. If you combine them with other material, the radioactive material will remain unaffected as regards its radioactivity. Recall that radioactivity is related to the instability of atomic nuclei, and the atomic structure of atomic nuclei are (in general) not involved in chemical bonding. Chemical bonding doesn't affect the stability of the nuclei of atoms. If they are unstable, they will remain so whether the atoms are alone or chemically combined with something else.
It is supposed that ununseptium is a halogen (non metal).
most elements are non metal
