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 … WebThis video explains how elements in Period 3 and below can expand their octet to allow for bonding with other atoms and having more than 8 electrons in their...
Can as form compounds with an expanded octet? – Short-Fact
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 … WebMay 14, 2012 · See answer (1) Copy. Elements which have d-orbitals (i. e. n=3 or higher) can form compounds with an expanded octet. Some examples are; Phosphorous … how much pesos is 2400 robux
How to know when to expand an octet - CHEMISTRY …
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 electrons. Expansion of octet is possible only from Period 3 elements onwards, due to the presence of low-lying empty d orbitals that can accommodate the extra electrons. 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. 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 … how do i write a church contribution letter
