What else can I help you with?
Which noble gas has the greatest atomic number?
That would be Astatine with the atomic number 85.
What is the heviest noble gas?
Noble gases belong to group 0 and can be found on the extreme right column of the periodic table of elements. The heaviest noble gas would be radon, whose atomic mass is still uncertain. The element which appears below radon in the column, ununoctium, has not been confirmed as a noble gas.
What pattern is in a noble gas?
The atomic mass increases as you go down the group of Noble Gases.For example, helium is the first on down the group of Noble Gases. If you have a balloon full of helium, it would rise as it's atomic mass is the lightest of 4.002602 amu. Then, the furthest down the group of noble gases is radon. If you have a balloon full of radon, it would sink down immediately as it's atomic mass is 222.0 amu.
Who what is the heaviest of the naturally occurring noble gases?
Radon is the name of the heaviest noble gas.
What is a correct representation for a nuclide of radon?
A correct representation for a nuclide of radon in atomic symbol notation would be ^22286 Rn. This indicates that the nuclide has 222 nucleons (sum of protons and neutrons) and an atomic number of 86 (number of protons).

Which of the following are considered noble gases?
Helium, Neon, Argon and if another Krypton.

If a new element is discovered which resembles noble gases what would be its possible atomic number?
118 will be its atomic number.

How many electrons are in the -1 ion of radon?
Radon's atomic number is 86. Therefore, were it electrically neutral, radon would have 86 protons and 86 electrons. Since we're talking about Rn-1 though, we need to add an electron to that, bringing the total to 87.
In the formula XBr2 if the ion of element x has a mass of 230 and 86 electrons what is the identity of the element and how many neutrons does it have?
it would be an isotope of Radon, (Radon-230)
If the atomic number of Element D is 20 then what is the atomic number of R?
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).
Radon is an inactive gas what other elements would have properties similar to radon?
Other elements that would have properties similar to radon include other noble gases such as helium, neon, argon, krypton, and xenon. These elements are all inert and have low reactivity due to their stable electron configurations. Like radon, they are all colorless, odorless, and tasteless gases at room temperature.
