The electronic configuration of thallium lll ion is 4F^14 5D^10 and it has a charge of +3.
Thallium is a chemical element with the chemical symbol TI. Its atomic number is 81 and the atomic mass is 204. The charge of +3 implies that, the element will give away three electrons during the course of chemical reaction in order to attain stability.

The electronic configuration of thallium (iii) ion is [Xe] 4f¹⁴ 5d¹⁰ and its charge is +3

  • For the electronic configuration of thallium (iii) ion

Thallium atom has 81 electrons and its electronic configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p¹.

Thallium (iii) ion has lost 3 electrons from its outermost energy levels (6s and 6p). It lost 2 electrons from 6s and 1 electron from 6p. Therefore, the electronic configuration of thallium (iii) ion is  [Xe] 4f¹⁴ 5d¹⁰

  • For the charge of thallium (iii) ion

The charge of thallium (iii) ion is +3

Hence, the electronic configuration of thallium (iii) ion is [Xe] 4f¹⁴ 5d¹⁰ and its charge is +3
