Elements of Group 16 have the general valence shell electronic configuration $n{s}^{2}n{p}^4$.

To achieve the stable noble gas configuration ($n{s}^{2}n{p}^6$), they need to gain two electrons.

For example, Oxygen (Group 16) has the configuration $1s^{2}2s^{2}2p^4$. By gaining two electrons, it forms $O^{2-}$ with the configuration $1s^{2}2s^{2}2p^6$, which is the stable noble gas configuration of Neon.

Answer: Group-16
