a maximum of 2 electron can be carried by s so it will be 1s2 2s2 2p6 3s2 3p6
The rule that is violated in the configuration of 1s2 2s2 2px2 is the Hund's Rule. Hund's rule states that all electrons do not want to be with each other.
The investigator will find that 1s2 2s2 2p6 is the electron configuration for neon.
atoms in stable compounds almost always have a noble gas electron configuration or when representative metals and nonmetals react, thay transferelectrons in such a way that both th cation and the anion have noble gas electron configuration.
OCTET RULE:-The tendency of atoms to require eigth electron configuration in their valence shell, when bonding,is called octet rule.DUPLET RULE:-The tendency of atoms to require two electron configuration in their valence shell, when bonding,is called duplet rule
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.

Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
the electron configuration of a noble gas
if we find the electronic configuration, by 2n^2 rule, we can find it
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
The investigator will find that 1s2 2s2 2p6 is the electron configuration for neon.
atoms in stable compounds almost always have a noble gas electron configuration or when representative metals and nonmetals react, thay transferelectrons in such a way that both th cation and the anion have noble gas electron configuration.
The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.
It is called the octet rule.

They do, it's just that they do not follow the octet rule. You have to find the electron configuration to find the dot structure.
