SUMMARY

The Lewis diagram for TeCl4 reveals that tellurium (Te) donates four electrons to four chlorine (Cl) atoms, resulting in a total of 10 remaining electrons. This configuration leads to one lone pair of electrons on the tellurium atom, which contributes to the molecule's see-saw geometry. The misunderstanding arises from the initial assumption of Te's total electron count, which is 14, but only 6 electrons remain in the outer shell after bonding with Cl atoms.

PREREQUISITES
  • Understanding of Lewis structures
  • Knowledge of valence electrons and their role in bonding
  • Familiarity with molecular geometry concepts
  • Basic principles of electron pair repulsion theory
NEXT STEPS

  • Research the electron counting method for transition elements
  • Explore the properties and bonding of tellurium compounds
USEFUL FOR

Chemistry students, educators, and anyone studying molecular geometry and bonding theories, particularly in relation to transition elements like tellurium.

Homework Statement


I'm asked to draw the Lewis diagram of TeCl4.


Homework Equations





The Attempt at a Solution


As far as I understand, Te will give away 4 electrons to all the 4Cls. Since Te has 14 electrons, it leaves it with 10 electrons.

Why would i get 1 lone pair then? I'm not getting the why behind that.

Tellurium's outermost shell will have only 6 electrons and not 14. Minus the 4 given to the Cl atoms, you will be left with single pair. This results in a see-saw geometry.
