The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block).

∙ 10y agoOne definition of pseudo noble gas refers to ions that have a nobele gas core with a filled d orbital sub shell , d10
exaples:
In+ [Kr], 5s2 4d10
In3+ [Kr] 4d10
The ionization energy to remove a d electron is too high.
The same is true for gallium and thallium.
