Radon Element (Periodic Table)

Radon

Radon (Rn) is a chemical element of the periodic table, located in the group 18 and the period 6, and is having the atomic number 86. It is a colorless, odorless, tasteless gas, whose name comes from the Latin word “nitens”, which means shining. It is a member of the noble gas group and is counted as one of the radioactive elements.
