What is pseudo noble gas configuration?
Pseudo noble gas configuration:
The [noble gas ] (n-1)d10 electron configuration is known as a pseudo noble gas configuration because several cations with this arrangement of electrons are stable.
For example, both InCl and InCl3 are stable compounds.
to form In+ only the 5p1 electron is removed leaving the [Kr] 5s2 4d10 electronic configuration.
