they are all completely filled in the case of noble gases
s orbital for helium and p orbitals for other noble gases.
The elements that have highest occupied s and p sublevels partially filled are called the representative elements. These include Groups I and II and the last six groups on the right of the periodic table.
The valence electron shell of noble gases is full.
For noble gases, the outermost s and p sublevels are already filled with electrons. This is what gives them their stable configuration and makes them generally unreactive.
helium has the least density, xenon has the highest.
a filled highest occupied principal energy level
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
noble gases
Krypton belongs in the noble gases group because it has a full valence shell of electrons, making it stable and unreactive. It does not readily form compounds with other elements due to its stable electron configuration, similar to other noble gases.
Another word for a noble gas is an inert gas. These elements have the maximum electrons in their highest energy level.
All noble gasses have 8 valence electrons, it is what makes them "stable" and therefore are non reactive.
the elections with the highest energy are in an f sub level. your welcome :))
