The number of electrons in the atom comprised the atomic number and the electronic configuration. The ionic species that lacks the same configuration as Kr is potassium ion.
What is atom?
An atom is the smallest unit of the matter with the presence of electrons, protons and neutrons as the subatomic particles. The electrons are present in the orbital and the loss and gain of the electrons adds charge to the atom.
The number of electrons in Kr atom is 36. The number of electrons in the following species is:
[tex]\rm Br^-=36\\Sr^{2+}=36\\K^+=18\\Rb^+=36\\[/tex]
Thus, the atom or ionic species that lacks the same configuration as Kr is potassium ion.
