Explain Isoelectronic Ions
If two or more molecules share the same structure and have an equal number of valence electrons, they are said to be isoelectronic.
- Na+ ion's electronic configuration is 2,8.
- O- ion's electronic configuration is 2,7.
- O2- ion has an electrical configuration of 2,8.
- They have therefore filled the K and L shells because they each have 10 electrons.
- It isoelectronic for Sp, Na+, and O2.
- This means that while the connectivity and atom count are the same, the elements may not be the same.
In which of the following pairs are the ions isoelectronic? (I) Mg2+, Ar (II) Na+, O2- (III) Al3+, Cl- (IV) K+, Ne
Na+, O2- the ions are isoelectronic in given pairs. The molecules or ions which share the same electronic structure and valence electron count is called as isoelectronic.
