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 2, 2024 · Atoms in these periods may follow the octet rule, but there are conditions where they can expand their valence shells to accommodate more than eight electrons. Sulfur and phosphorus are common examples of this behavior. Sulfur can follow the octet rule as in the molecule SF2. Each atom is surrounded by eight electrons.

WebAn element from Period 3 and belowwill be able to expand octet by making use of its energetically accessible, or low lying d-subshell for bonding. This means only Period 2 elements such as C, N, O and F cannot expand octet and have to obey octet rule. Which elements can have an expanded octet Why? WebWhen an atom can have more than 8 valence electrons, it forms an expanded octet. Arsenic is bonded to 5 chlorine atoms and has an electronic configuration of [Ar] 3d¹⁰ 4s² 4p³. To create 5 bonds with chlorine atoms, it has to utilize its d-orbitals, allowing it to fit more than 8 electrons in its valence shell. WebOct 7, 2024 · Species with Expanded Octets .
