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 5, 2024 · An expanded valence shell is known to be where more than eight of an atom's electrons are together in covalent bonding.Sulfur can have an expanded valence shell.. Elements that cannot have an expanded . octet are: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen oxygen, fluorine, neon etc.. The octet rule can be …
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. WebMar 29, 2015 · What is the highest possible expanded octet? Often called "hypervalent", chemicals like phosphorous pentachloride and sulfur hexafluoride are possible due to the …
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. … 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.
