Seo42 Lewis Structure -

At this point, every oxygen has an octet. But selenium currently has only 8 electrons around it (4 bonds), which is an octet as well. However, Se is in period 4 and can expand its octet due to available d-orbitals.

Slightly less than 120° (due to the repulsion from the lone pair on the Selenium atom). Why the SeO₂ Structure Matters seo42 lewis structure

The SEO42- Lewis structure, also known as the selenium trioxide or selenium dioxide dimer, is a molecular structure that represents the composition of selenium and oxygen atoms. At this point, every oxygen has an octet

$$SeO4^2- = Se(\ddotO)_4^2-$$

The Lewis structure of SeO42- (selenate ion) consists of: At this point
