Radon (symbol Rn) is element number 86 of the periodic table and belongs to the “Noble gas” category. Its atomic mass is about 222, and its phase under standard conditions is Gas. This element sits in period 6 and group 18 of the periodic table, and its electrons are arranged in shells of 2, 8, 18, 32, 18, 8. The short electron configuration of Radon is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁶. Known uses of Radon include Cancer treatment and Scientific research.
The electron configuration of Radon (Rn), with 86 electrons, is shown below. The last shell (shell 6) is highlighted:
Distribution of 86 electrons of Radon across shells K to P:
The noble gases are the group 18 elements: their outer shell is full, so under normal conditions they are very unreactive.
The atomic number of Radon (Rn) is 86; that is, every atom of it has 86 protons.
The electron configuration of Radon (Rn) is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 4f¹⁴ 5s² 5p⁶ 5d¹⁰ 6s² 6p⁶; in short form it is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁶, and its last shell is 6s² 6p⁶.
