(a)
Interpretation: Ground-state electronic configuration of the given set of metal ions has to be written.
Concept Introduction:
- Electronic configuration is the arrangement of the electrons of atoms in the orbital. For atoms and ions the electronic configuration are written by using Pauli Exclusion Principle and Hund’s rule.
- According to Pauli Exclusion Principle, no two electrons having the same spin can occupy the same orbital.
- According to Hund’s rule, the orbital in the subshell is filled singly by one electron before the same orbital is doubly filled. When the orbitals are singly filled, all the electrons have same spin. In a doubly filled orbital, there are two electrons with opposite spin.
- Half-filled orbitals are comparatively stable as completely filled orbitals. Therefore if there is a possibility of forming half filled orbital then the electron will be moved to the respective orbitals giving rise to more stability.
- When cation is formed it means the electrons are removed from the outermost orbital of atom. If anion is formed means then the electrons are added to the atom in its outermost orbital.
