In the H2TeO4 molecule, the Te atom is the central atom.

Draw a Lewis diagram of H2TeO4 for which all formal charges are equal to zero. How many double bonds are there in the structure that you have drawn?

number of double bonds = ___01234

Draw a Lewis diagram in which the octet rule is satisfied on all atoms. What are the formal charges on the following atoms in the structure that you have drawn?

Te  
hydroxyl O  
terminal O  



Based on formal charge, which is the best Lewis structure for the molecule?

Expert Answer

Step 1

We'll answer the first question since the exact one wasn't specified. Please submit a new question specifying the one you'd like to get answered.

Formal charge is defined as the charge assigned to an atom, assuming that the electrons are shared equally. Formal charge (FC) is calculated as:

Step 2

In H2TeO4 molecule, 

Te lies on group 16. Its outer electronic configuration is:

Te : 5s2 5p4

Thus, Te has 6 valence electrons

Outer electronic configuration of O

O; 2s2 2p4  : O has 6 valence electrons

Electronic configuration of H : 1s

Thus, H has 1 valence elctrons

Step 3

Thus, Lewis structure of H2TeO4 with zero formal...
