Find out the total number of cation(s) which has/have pseudo inert gas electronic configuration.

Zn²⁺, Cd²⁺, Ag⁺, Cu⁺, Cu²⁺, Ca²⁺, Hg²⁺, Ga⁺, Ga³⁺

[Given atomic number of element is Zn = 30, Cd = 48, Ag = 47, Cu = 29, Ca = 20, Hg = 80, Ga = 31]

Answer:
6.00
Solution:

A pseudo inert gas configuration is .

Zn²⁺: [Ar]3d¹⁰ (pseudo inert)

Cd²⁺: [Kr]4d¹⁰ (pseudo inert)

Ag⁺: [Kr]4d¹⁰ (pseudo inert)

Cu⁺: [Ar]3d¹⁰ (pseudo inert)

Hg²⁺: [Xe]4f¹⁴5d¹⁰ (pseudo inert)

Ga³⁺: [Ar]3d¹⁰ (pseudo inert)

Cu²⁺, Ca²⁺, Ga⁺ do not have this configuration.

Total = 6.
