Isotopes are not designated by atomic number. The element with atomic number 88 is Radium. Because different isotopes of the same element vary by the number of neutrons in the nucleus, the isotope is designated by the Atomic Mass. For example, most carbon atoms have six protons, so the atomic number is 6. The most common isotope has 6 neutrons, so the isotope (Carbon 12) is the same as the atomic mass, 12 (6P + 6N), but there are isotopes with atomic masses of 13 (6P + 7N) and 14 (6P + 8N). Carbon 14 is familar as a dating tool when organic compounds are present. The only isotope given for Radium in the Periodic Table is 266.
The atomic number of radon (Rn) is 86. Therefore, the atomic number of 222Rn is also 86, indicating that radon has 86 protons in its nucleus.
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
Radon has 86 protons (atomic number 86).
Radon has atomic number 86. That means it has 86 protons. The specific isotope doesn't matter. (It does matter if you want to figure out the number of neutrons, though.)
Nitrogen has a much smaller atomic number, specifically 7, than either chromium (24) or radon (86).
The atomic number of radon (Rn) is 86. Therefore, the atomic number of 222Rn is also 86, indicating that radon has 86 protons in its nucleus.

The atomic number for radon is 86.
Radon has 86 protons (atomic number 86).
Radon has atomic number 86. That means it has 86 protons. The specific isotope doesn't matter. (It does matter if you want to figure out the number of neutrons, though.)
Radon is a non metal element. Atomic number of it is 86.
We can find radon as a non metal element. Atomic number of it is 86.
Nitrogen has a much smaller atomic number, specifically 7, than either chromium (24) or radon (86).
Radon atomic symbol: Rnatomic number: 86
From atomic number 55 to 86
Redon is a none metal element. atomic number of it is 86.
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
