Identify the ions, each with a net charge of +1, that have the following electron configurations: (a) [Ar], (b) [Ar]3d10, (c) [Kr]5s24d10, (d) [Xe].
(a)
Interpretation: Ions with a +1 net charge need to be identified for the given set of electronic configurations.
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 is singly filled, all the electrons have same spin. In a doubly filled orbital, there are two electrons with opposite spin.
- 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.
- For simpler representation of ions or atoms, the electronic configuration of the completed octet noble gas configuration is considered and the remaining orbital alone is shown explicitly.
