Do you know Lewis structure of ClO4^-? The Lewis structure of AtO4^- will be similar: just put At in place of Cl.

Formal charge: +1

Electron pair geometry: tetrahedral

Molecular geometry: tetrahedral

hey thnx but how did u get FC of +1 , its tetrahedral so shouldn't it be like 7-0-4=3 i knw i am wrong but could u explain how did u get +1?

Which of the following clusters of orbitals would form the shape shown here (Part A 1 figure) and would also be possible within the valence shell of an atom?

Check all that apply.

two p orbitals one sp^2 orbital and one p orbital four sp^2 orbitals four sp^3 orbitals (correct) one d orbital four sp^3d orbitals (correct) four p orbitals two sp orbitals

figure is as follows
