Can na have an expanded octet
WebFeb 20, 2024 · To have an expanded octet (more than 8 electrons) you need more than 4 orbitals. This means that you need to start using d-orbitals, and those are only available for atoms in the third period or below (So atoms in the third period or greater can have expanded octets. WebDec 5, 2024 · Hi Anne, When making Lewis structures, some atoms will expand its octet in order to lower the formal charge of the overall molecule. Atoms want a formal charge of 0 as it's the most stable. Elements that have a 3p subshell can expand its octet (elements in Period 3 and lower). This is because atoms from Period 3 and below can use …

WebNov 7, 2024 · When to expand an octet. 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 … WebThe octet rule can be 'expanded' by some elements by utilizing the d-orbitals found in the third principal energy level and beyond. Sulfur, phosphorus, silicon, and chlorine are …

WebThe Octet Rule and Its Exceptions. The octet rule states that atoms below atomic number 20 tend to combine so that they each have eight electrons in their valence shells, which gives them the same electronic configuration as a noble gas. The rule is applicable to the main- group elements, especially carbon, nitrogen, oxygen, and the halogens ... WebJul 7, 2024 · Can Period 2 have expanded octets? Expansion of the valence shell is impossible for an atom in the second period because there is no such thing as a 2d …
WebExpanded octet occurs when an atom is able to have more than 8 valence electrons. For example, in SO₃, the sulfur atom forms 6 covalent bonds, hence it has 12 valence …

Answer: Elements in the 3rd row, 4th row, etc., can have an expanded octet due to d-orbitals. Since Xe is in row 5 it has d-orbitals that can accomodate additional electrons. Top. diamond dealers portland oregonWebthe octet rule has exceptions because not all atoms have 8 electrons surrounding them. 1. odd octets: electron species, molecules, or ions with off number of electrons (ex. NO) 2. incomplete octets: molecules or ions with fewer than 8 electrons around an atom (ex. BF3) 3. expanded octets: molecules or ions with more than 8 electrons around atom (ex. AsF5) diamond deangelis constructionWebNov 6, 2024 · Expanded octets are possible for elements with more than 8 valence electrons. In order to have more than 8, the atom has to put electrons in the d subshell.
