What ions have a pseudo noble-gas electron configuration?
A pseudo-noble-gas configuration has the form s2 p6 d10. It has 18 electrons in the outer energy level and is a relatively stable configuration. Examples of ions with this configuration are Ag+, Cu+, Cd2+, and Hg2+.

How do you calculate pseudo inert gas configuration?
The configuration of an ion of an element in which the shell with the highest energy level has 18 electrons instead of 8 electrons is called Pseudo inert gas configuration. Elements having d orbital also filled along with the s and p orbital are said to have pseudo gas configuration.
What is pseudo noble configuration?
Pseudo – inert gas configuration means having 18 electron instead of 8 electrons in (n−1) shell electronic configuration after gaining or loosing electron. This configuration is called as pseudo noble gas configuration .
What is pseudo noble gas?
Pseudo – inert gas configuration means having 18 electron instead of 8 electrons in (n−1) shell electronic configuration after gaining or loosing electron. The ions of certain elements are stable as they have a complete valence shell but do not have the configuration of a noble gas .
What is the formula of the ion formed when sodium achieves a stable electron configuration?
d. A phosphorus atom has 5 valence electrons and gains 3 electrons to attain a noble-gas configuration. The formula of the ion formed is P3-. State the number of electrons either lost or gained in forming each ion.
What is the formula of the ion formed when phosphorus forms an ion?
Phosphide

What do you mean by noble gas core and pseudo noble gas core?
The pseudo noble gas core is an inner shell configuration corresponding to one of the noble gases together with (n-1)d10 electrons. This is because these electrons usually are not involved in chemical reactions. For example, Gallium (Z=31) has an electronic configuration of [Ar] 3d10 4s2 4p1.
