Noble gases

Postby Lelija Kazlauskas 3J » Sun Nov 17, 2019 5:59 pm

Why would a noble gas like xenon form a covalent bond? It's valence shell is already full.

This occurs because some elements are able to have an expanded octet. This occurs when the valence shell has enough orbitals to accommodate for the additional electrons.

Xeon and other noble gases with 8 electrons in their valence shells can still form covalent bonds because of their expanded octet.

Noble gases from the 3p orbital onwards are able to have an expanded octet because the electrons can expand into the d subshell. As a result, xenon is able to form a covalent bond because it can expand its octet.
