Mo^3+ = [Kr] 4d^3
The trivalent ion with the electron configuration of Kr 4d^3 is the Yttrium (Y^3+) ion. Yttrium differs from krypton (Kr) by losing three electrons to achieve the electron configuration of Kr 4d^3.
Boron forms a tripositive ion (B3+) because it has three valence electrons that it can lose to achieve a stable electron configuration. By losing these three electrons, boron can attain a full outer shell of electrons, which is energetically favorable.
The electron configuration of boron is 1s2 2s2 2p1. When boron becomes an ion, it typically loses its outer electron to achieve a stable electron configuration. Therefore, the electron configuration of a boron ion is typically 1s2 2s2.
The He+ ion (helium ion) has the same electron configuration as an atom of helium (He) because it has lost one electron, making it a 1+ ion. Both the helium atom and He+ ion have a total of 2 electrons arranged in the 1s orbital.
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
The electron configuration for a potassium ion (K+) is [Ar] 4s1. Potassium loses one electron to form the +1 ion, resulting in a noble gas configuration like argon.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
The ion with a -2 charge that has the same electron configuration as krypton is Oxygen. Both krypton and an oxygen ion with a -2 charge have the electron configuration of 2-8-18-8.
