Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
Radon has 86 protons in it's nucleus.
Copper. It has 29 protons, sodium has 11 protons, and radon has 86 protons.
Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
The chemical element, Radon, has an atomic number of 86, meaning it has 86 protons. Were there an isotope of Radon that had 136 neutrons, it would be labeled as 222Rn. Well, it turns out that this isotope does exist and has a half-life of 3.82 days.
The number of protons is the same as the elements Atomic Number (86). So you can look it up on the Periodic Table.Element 86 is the gas Radon.NOTE is it NOT in period 4 it is in period 6
The element that has 86 protons in period 6 is Radon (Rn).
The element with 86 protons in period 6 is radon, which has the chemical symbol Rn. It is a radioactive noble gas that is found in trace amounts in the Earth's atmosphere.
Radon Rn
Radon has 86 protons in it's nucleus.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
Copper. It has 29 protons, sodium has 11 protons, and radon has 86 protons.

Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
86 - Atomic Number ( Number of Protons )RN (Radon)222 - Mass Numberatomic number 86 - a radioactive gaseous element formed by the disintegration of radium; the heaviest of the inert gasses; occurs naturally (especially in areas over granite) and is considered a hazard to health.
