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?
Noble gases have a full outer electron shell, which makes them highly stable and unreactive. This electron configuration is known as the octet rule or the noble gas configuration, and it is a pattern observed in all noble gases.
Who what is the heaviest of the naturally occurring noble gases?
Radon is the name of the heaviest noble gas.
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.

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.

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.
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.
What are five elements that are noble gases?
I think it would be easier to say what gases ARE noble gases. The six noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. Any other elements are not Noble gases. This can include elements like Gold, Mercury, Calcium, Potassium, and barium.
What element is formed when Ra emits an alpha particle?
Next element in the periodic table ie Actinium.
