WebThe selenium atom in the SeF6 Lewis structure shows an exception and accommodates 12 electrons (6 valence electrons of fluorine and 6 valence electrons of its own). So it is a hypervalent species and can expand its octet due to the availability of vacant d orbitals. SeF6 Lewis structure shape WebIn solid-phase SeO3 lewis structure is in the form of cyclic tetramer comprising of (Se-O)4 8 membered rings. As the Se atom in these tetramers is 4-coordinated, the bond length of bridging Se-O and non-bridging Se-O varies a lot. The …
