In krypton atoms, the 3s and 3p sublevels are filled, i.e. 3s23p6.
filled energy sublevels
3, three, tres
some elements have unusual atomic orbitals
Lyman's series
Atoms, like Neon (Ne), that have the s and p sublevels filled with either electrons are said to have an "octet" of electrons.

The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
Argon is the noble gas in third period. In modern periodic table, it is in group 18. It bears [Ne] 3s2 3p6 electron configuration.
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
krypton is a nonmetal
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
Atoms, like Neon (Ne), that have the s and p sublevels filled with either electrons are said to have an "octet" of electrons.
s block element-s block element is the highest occupied energy level is s-sublevels which is partially filled or just completed p-in a p block p sub levels is the highest occupied energylevelthe general electronicconfiguration in outershell is ns2
All the noble elements to the far right of the periodic table have their s and P sublevels in their valence shell filled, hence they are nonreactive.
