The externall shell of electrons is completely filled.
Transition metals, lanthanides, and actinides do not typically have a noble gas electron configuration due to the presence of partially filled d or f orbitals. These elements have unique electron configurations that differ from the stable octet or duet configurations of noble gases.
None of the noble gases have 5 sublevels. All noble gases have electron configurations that end in an s or p sublevel.
They achieve noble gas configuration by the sharing of electrons.
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
Writing at the beginning the adequate symbol of an noble gas, in square parenthesis.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
Transition metals, lanthanides, and actinides do not typically have a noble gas electron configuration due to the presence of partially filled d or f orbitals. These elements have unique electron configurations that differ from the stable octet or duet configurations of noble gases.
Atoms achieve noble gas configurations in single covalent bonds by sharing electrons between them, forming a stable electron configuration similar to a noble gas. This sharing allows both atoms to attain a full outer shell of electrons, satisfying the octet rule.
None of the noble gases have 5 sublevels. All noble gases have electron configurations that end in an s or p sublevel.
They achieve noble gas configuration by the sharing of electrons.
Noble gas notation is a way of simplifying electron configurations by using the previous noble gas's electron configuration as a starting point. For calcium, the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. Using the noble gas argon (1s2 2s2 2p6 3s2 3p6) as the starting point, the noble gas notation for calcium is [Ar] 4s2.

Two atoms share two electrons.
The noble gas electron configuration of selenium is [Ar] 3d^10 4s^2 4p^4 and for phosphorus is [Ne] 3s^2 3p^3. These configurations indicate how the electrons are arranged in the outermost energy levels of the atoms, resembling the stable electron configurations of noble gases.
