Can na have an expanded octet

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. 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)

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. 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 ... fnf playground 2 kbh https://eastwin.org
