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. Webfew exceptions to the octet rule. 1. hydrogen and helium follow the duet rule. 2. in molecules that have odd amounts of electrons, there is no way to give every atom a full octet. 3. elements in the second row and below can have expanded octets, more than 8 electrons. odd-electron molecules. odd-electron molecules will have one atom with an ... WebThe octet rule is a concept in chemistry. It allows us to determine the atomic structure of most chemicals. The octet rule is also used in determining the names and formulas for many chemicals. As you might suspect, the octet rule is based on the number 8. It is a direct consequence that the periodic table has 8 main columns (the ones near the ... how many doctors appointments for newborns

WebOnce we know how many valence electrons there are in BrF5 we can distribute them around the central atom with the goal of filling the outer shells of each atom. Note that in the Lewis structure for BrF5, Bromine (B) is in Period Four on the periodic table. This means it can hold more than eight valence electrons. This is called an expanded octet. WebFluorine is a second period element which can only contain a maximum of 8 valence electrons. Xenon meanwhile can have an expanded octet and can hold more than 8 electrons. Basically any of the fluorine atoms wouldn't be able to hold onto an extra 2 electrons which only leaves the central xenon atom with the ability to.
