Expanded octet periodic table

Web1) Odd octets, seen in electron species, molecules, or ions with an odd number of valence electrons (NO). 2) Incomplete octets, seen in molecules or ions with fewer than 8 electrons surrounding an atom (BFsub3). 3) Expanded octets, seen in molecules or ions with more than 8 electrons surrounding an atom (AsFsub5). Click the card to flip 👆. 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:

Any elements with an atomic number larger than 10 have access to the d orbital and can have an expanded octet. Any elements with unfilled d orbitals can have expanded octet. Elements that are in period 3 and beyond have the capacity to have an expanded octet. 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. gingerbread design on house

WebDec 1, 2024 · Expanded octets exist because elements with a d-orbital can can store more electrons than the 8 spots usually limited by the s + p orbitals. Thus, expanded octets would be reserved for elements from period 3 of the periodic table and onward, since these are the elements with d orbitals gingerbread dice game printableWebThe octet rule is based on the fact that each valence orbital (typically, one ns and three np orbitals) can accommodate only two electrons. To accommodate more than eight electrons, sulfur must be using not only the ns and np valence orbitals but additional orbitals as well.
