WebNote that when an expanded octet is in an anion, one or more other atoms will have the improper number of lone pairs and bonding pairs. Two oxygen atoms in each of these ions happens to be that way. Selenium is in the same group on the periodic table as sulfur and thus follows the same pattern of expanded octets and number of bonding pairs: WebAtomic radius is one periodic property of the elements. Atoms become smaller from left to right across a row, but they become larger going down a column. The largest atoms are thus found in the bottom left corner of the periodic table.

If central atom does not have octet, bring in electrons from outside atoms to share. 7. Assign formal charges to the atoms. WebNov 2, 2024 · Re: Extended Octet for Sulfur. Sulfur can have an expanded octet because it is in Row 3 of the periodic table, meaning that the quantum number n is equal to 3. When n=3, l can be 0, 1, or 2 according to the rules for quantum numbers. This means that elements in Row 3 have the S, P, and D subshells available to them to hold electrons.
