What element is a gas in period 6 and has 86 protons?
Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
What element is a noble gas in period 6?
The element Radon (atomic symbol Rn) is the noble gas found in Period 6 of the periodic table.
How many proton their are in radon?
Radon has 86 protons (atomic number 86).
Number of protons in a radon atom?
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
What is the atomic number of radon?
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
What is period 6 it is a gas and has 86 protons?
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
What element is a gas in period 6 and has 86 protons?
Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
What element has 86 electrons?
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.
How many subatomic particles does radon have?
Radon has 86 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a radon isotope = Mass number - 86
What element is a noble gas in period 6?

How do you Eliminate radon from drinking water?
Radon is an important problem for the atmosphere in the buildings not for the water. Radon from the water can be eliminated by boiling the water. Also because the most important isotope pf radon, 222Rn, has a half life of only 3,8235 days radon disappear after a period of time.
