The element radium (symbol Ra) is in period 7.
The element is radon (Rn), which has 86 protons. Radon is a noble gas that is located in period 6 of the periodic table.
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
The element Radon (atomic symbol Rn) is the noble gas found in Period 6 of the periodic table.
Radon has 86 protons (atomic number 86).
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
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 is radon (Rn), which has 86 protons. Radon is a noble gas that is located in period 6 of the periodic table.
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
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
The element Radon (atomic symbol Rn) is the noble gas found in Period 6 of the periodic table.
We can find radon as a non metal element. Atomic number of it is 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.
Radon has 86 protons (atomic number 86).
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
Radon Rn
To type the chemical symbol for Radon with its mass and atomic number on a computer, you can use the following format: ^222Rn. This notation indicates that Radon has an atomic number of 86 and a mass number of 222.
Nitrogen has a much smaller atomic number, specifically 7, than either chromium (24) or radon (86).
