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.
A noble gas electron configuration involves representing an element's electron configuration by using the electron configuration of the nearest noble gas preceding it in the periodic table, followed by the remaining electron configuration for that element. For example, the noble gas electron configuration for sodium (Na) is [Ne] 3s¹, where [Ne] represents the electron configuration of neon leading up to sodium.
Radium is a highly reactive element and does not typically exhibit a noble gas configuration. Noble gases have a full outer electron shell, which makes them stable and unreactive. Radium, on the other hand, is a highly radioactive element and is part of the alkaline earth metal group, so it tends to lose its outer electrons rather than achieve a noble gas configuration.
Noble gases have a complete set of valence electrons, typically filling their outermost electron shell, which makes them highly stable and unreactive compared to other elements. This full valence shell is the reason they do not readily form bonds or react with other elements. In contrast, other elements often have incomplete valence shells, driving them to react and achieve a more stable electron configuration similar to that of noble gases. Thus, the key difference lies in the stability provided by a complete valence shell, characteristic of noble gases.

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.

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.
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.
The noble gas configuration for xenon (Xe) is [Kr] 5s² 4d¹⁰ 5p⁶. Other elements that have the same noble gas configuration as xenon include radon (Rn), which is directly below xenon in the periodic table, and elements that are isotopes of xenon with different neutron counts, though they are still considered the same element.
