Expanded octet

Postby Jordan_Wesson_2J » Thu Nov 08, 2018 11:13 am

Why can an expanded octet have 10,12... electrons when octets always need exactly 8?

electrons in the 3rd period and on can take advantage of their empty d orbital and use it to hold electrons and make themselves more stable by reducing their formal charge (resulting in going over the 8 that gets held by the p+s orbitals)

Because when molecules have access to the d orbital they are able to store more electrons.

Since expanded octets apply to all elements Period 3 and on, they have access to their d-orbitals to form more bonds.

Elements in period 3, 4, ... and so on can have an expanded acted with more than 8 electrons because the electrons will be filled into the d orbital.
