WebSep 22, 2024 · One exception to the octet rule is that in the real world some atoms in molecules or compounds do have fewer than eight (octet) valence electrons. Some examples of these include: Hydrogen (H) in H … WebMay 30, 2024 · Which elements can exceed the octet rule? Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl 5 ) and sulfur hexafluoride (SF 6 ) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.
What is the covalency of chlorine? - Quora
WebOct 10, 2024 · Chlorine has seven valence electrons, so if it takes one it will have eight (an octet). Chlorine has the electron configuration of argon when it gains an electron. The octet rule could have been satisfied if chlorine gave up all seven of its valence electrons and sodium took them. In that case, both would have the electron configurations of ... WebA valence bond description that preserves the appropriate number of electrons at Cl (i.e. Cl atom double bonded to 2 O's, singly bonded to 3 O's) would then have to exist as a … portillo\u0027s stock price prediction 2025
General Chemistry/Octet Rule and Exceptions - Wikibooks ...
WebThe octet rule reflects the observation that the most stable ions of many elements have eight electrons in their valence shell for gaining the best possible stability.. Chlorine, for example, typically forms an anion with a charge of \(-1\), while sodium typically forms a cation with a charge of \(+1\). These patterns can be used to predict how elements will … WebThe octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. An exception to an octet of electrons is in the case of the first noble gas, helium, which only has two valence electrons. This primarily affects the element hydrogen, which forms stable ...
