WebA: Click to see the answer. Q: Explain why phosphorus can have an expanded octet but nitrogen can't. A: An atom that has more than an octet (can accommodate more than 8 electrons) in its valence shell, is…. Q: 3. (a) What is the octet rule? (b) How many electrons must a sulfur atom gain to achi an octet in…. WebThe octet rule states that atoms with an atomic number below 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, but also to metals such ...

WebNov 15, 2024 · Any element in period 3 or below (4, 5, etc.) can have an expanded octet because there are d-orbitals starting with period n = 3. Hi, to add on, Be, Li, H, He, and radicals are also exceptions to the octet rule. Radicals are compounds with unpaired electrons. Hope this helps! nys testing schedule 2022
The Octet Rule: Definition & Examples StudySmarter
WebNitric oxide has the formula NO. The total number of valence electrons is 5+6=11. Therefore, no matter how electrons are shared between the nitrogen and oxygen atoms, … WebOdd-electron molecules represent the first violation to the octet rule. Although they are few, some stable compounds have an odd number of electrons in their valence shells. With an odd number of electrons, at least one atom in the molecule will have to violate the octet rule. Examples of stable odd-electron molecules are NO, NO 2, and ClO 2. WebExpert Answer.
