They achieve noble gas configuration by the sharing of electrons.
Writing at the beginning the adequate symbol of an noble gas, in square parenthesis.
They are all members of the noble gas group (group 18).
Noble Gas Configurations
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.

They share an outer electron.
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.
They achieve noble gas configuration by the sharing of electrons.
octet rule
Two atoms share two electrons.

Because it is shorter and easier to write. Also saves time when compared to writing the complete electron configuration.
