They either gain electrons or lose electrons (which ever one that requires the least)
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.
For helium it is 1s2. For the other noble gases it will be ns2 np6 where n is the period in which the noble gas in present.
It's fullfill electronic configuration i.e ns2np6 configuration.
Due to their electron configuration, the atoms in a noble gas hardly attract each other.
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.

Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic 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.

They usually achieve "Noble Gas" configuration
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Yes helium is a noble gas because it is very stable, colorless, odorless taste less, but unlike the other noble gases, it has two electrons in its valence shell.
