WebMay 8, 2024 · In expanded octets, the central atom can have ten electrons, or even twelve. Molecules with expanded octets involve highly electronegative terminal atoms, and a nonmetal central atom found in the third period or below, which those terminal atoms bond to. For example, \(PCl_5\) is a legitimate compound (whereas \(NCl_5\)) is not: WebThis means only Period 2 elements such as C, N, O and F cannot expand octet and have to obey octet rule. Take note octet rule is the exception and not the norm, as most of the elements in the Periodic Table are Period 3 and beyond, so therefore can expand octet if necessary. Let's consider the electronic configuration of oxygen, a Period 2 element.

So for question 3.93 part (b) is asks us to draw the Lewis structure and all resonance structures for BrO+. Since Bromine can have an expanded octet, why wouldn't there be a resonance structure that has a triple bond between O and Br, then 2 lone pairs on Br, and one lone pair on O. Do expanded octets … 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. phone link app alternative
