Chemistry Question on Molecular Orbital Theory

Mg2+Mg ^{2+} is isoelectronic with

A

Cu2+Cu ^{2+}

B

Zn2+Zn^{2+}

C

Na+Na^{+}

D

Ca2+Ca^{2+}

Answer

Na+Na^{+}

Explanation

Solution

Isoelectronic species have same number of electron. Mg2+(12−2)Mg ^{2+}(12-2) and Na+(11−1)Na ^{+}(11-1) both have 1010 electrons hence, they are isoelectronic species.
