<u>Answer:</u> The electronic configurations of thallium ions is given below.

<u>Explanation:</u>

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

Ions are formed when an atom looses or gains electrons.

  • When an atom looses electrons, it will form a positive ion known as cation.
  • When an atom gains electrons, it will form a negative ion known as anion.

An element thallium having atomic number as 81.

Number of electrons = 81

Electronic configuration of thallium is: (Z=81):[Xe]4f^{14}5d^{10}6s^26p^1

The stable oxidation states of this element are +1 and +3.

So, the electronic configuration of Tl^+\text{ ion}=[Xe]4f^{14}5d^{10}6s^2

The electronic configuration of Tl^{3+}\text{ ion}=[Xe]4f^{14}5d^{10}

Hence, the electronic configurations of thallium ions is given below.
