Radon
Noble gases with atomic numbers 2, 10, 18, 36, 54 and 86 are known. The next in the series will be element with atomic number 118.
Radon has the largest atomic radius among the noble gases due to the increased number of electron shells, causing the atoms to be larger in size.
Radon is the largest noble gas element in terms of atomic size.
118 will be its atomic number.
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
Helium has the atomic number of 2. It is in the group noble gases. It is classified as a non-metallic substance.
Z is atomic number, so from the periodic table, you can see that this is the element krypton, Kr. You can also see that this element is in Group 18 (VIIIA), which is the noble gases group.
Yes. all are mono atomic
Noble gases have larger atomic radii than alkali metals in the same period.
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
The noble gases from the least atomic number are, helium, neon, argon, krypton, xenon and redon.
Krypton is an element, a noble gas, atomic number 36. It is one of the few noble gases to have been successfully bonded with another element; KrF2, krypton difluoride, can be produced in small quantities under extreme simulated conditions.
