They achieve noble gas configuration by the sharing of electrons.
Noble Gas Configurations
Pseudo noble gas configurations for cations are achieved by removing electrons from the highest energy levels first. For example, for the cation Na+, the electron configuration can be represented as [Ne]3s1, where Ne represents the noble gas neon. This notation helps to show the remaining electrons in a shortened manner.
In the shorthand method for showing electron configuration, the noble gas preceding the element is used to indicate the core electrons (inner shell electrons), while the valence electrons are indicated by the remaining electron configuration. For example, the electron configuration of potassium (K) can be written as [Ar] 4s¹, where [Ar] represents the noble gas core configuration (argon's electron configuration).
They usually achieve "Noble Gas" configuration
The externall shell of electrons is completely filled.
They achieve noble gas configuration by the sharing of electrons.
Na, Rb, Al3+, and S2- do not have a noble gas configuration as they do not have the complete outer shell of electrons like a noble gas. O2, Br, Ca, and O2- have noble gas configurations as they either have a complete outer shell of electrons or have gained/lost electrons to achieve a stable 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.
Noble Gas Configurations
The electron configuration of the noble gasses are such that the valence shell (the outer most shell of electrons) is filled up with eight electrons. the outermost shell of electrons can only fit eight and the noble gasses already have all eight.

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.
No. Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
