Can na have an expanded octet
WebDec 1, 2024 · The reason why we have expanded octets is because of the d-orbital. The octet rule is due to the eight electrons allowed in the s and p orbitals, but when we get to the d-orbital, it can accommodate more than 8 electrons and can form an expanded octet. Top. Abhinav Amanaganti 3K. Posts: 54. Webthe 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)

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 … WebMay 13, 2024 · The element that can show an expanded octet in the list is Br.. Bromine has an electron configuration of [Ar] 3d¹⁰ 4s² 4p⁵.This means that still has accessible 4d orbitals to which electrons can be filled.This is the reason why it is able to expand its octet.. Recall that any element that has accessible higher energy orbitals to which electrons can …
WebNov 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. The d subshell starts at n=3, so the elements with electrons in the third principle energy level (3s,3p,3d) and above (n=4, n=5,...) can have an expanded octet. WebExpanded Octet. The octet rule is generally applied for the main group elements. As per the rule, the atom should contain eight electrons in its valence shell. However, this rule is sometimes broken by the elements like phosphorus, sulfur, etc., due to the presence of vacant d orbitals.
