Which elements atomic mass is 222 amu?
The element with an atomic mass of 222 amu is radon (Rn).
How do you type Radon with its mass and atomic number on computer?
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.
What is the weight of radon?
222 Amu (atomic mass units) Each isotope of radon has a different atomic mass; see the link. The density of radon is 9,73 g/L.
What is the noble gas with lowest atomic mass?
Atomic mass increases from top to bottom and left to right on the periodic table. In each row, the noble gasses have the highest atomic mass. As you travel down that column, also called a group or family, the noble gasses increase in atomic mass. The naturally occurring noble gas with the highest atomic mass is Radon (Rn; atomic mass = 211.4 amu). In 2002, the unstable element Ununoctium was synthesized, and although it is a member of group 18, it was later determined to be a solid at room temperature, so it is not classified as a noble gas.
Which halogon has the greatest atomic mass?
Radon, unless you count the synthetic Ununoctium. But because it is radioactive, highly unstable, and synthetic, I would discount it for now. It does however have the largest atomic mass for any known atomic substance. So, the answer is Radon.
What element Nobel gas with atomic mass of 226?
Radon has atomic mass of 222. There is isotope of Radon with mass number 226. Radon is a Nobel gas.
Which elements atomic mass is 222 amu?
The element with an atomic mass of 222 amu is radon (Rn).
What is radon's atomic mass?
Radon has 34 isotopes; each isotope has a different atomic mass. See the link.

What is the atomic number of radon?
The atomic number of radon is 86, which means that radon has 86 protons in its nucleus.
What is the weight of radium?
The weight of radium can vary depending on the specific isotope. For example, the most common isotope, radium-226, has an atomic weight of approximately 226 grams per mole.
How many protons are in element radon?
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
