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 diradical species which would probably be very unstable. Just because something can exceed the octet rule doesn't mean that there are now NO rules, an atom still cannot ... WebJul 21, 2024 · Which atoms can exceed the octet rule? Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.
If chlorine can exceed the octet rule, why is there no ClO5- ion?
WebThe Octet Rule -summary • The second row elements C, N, O, and F should always be assumed to obey the octet rule • The second-row elements B and Be often have fewer than 8 electrons around them in their compounds. These electron deficient compounds are very reactive • The second-row elements never, ever exceed the octet rule • Third-row and … 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 … iphone date and time on pictures
Why are hydrogen H and helium He exceptions to the octet rule?
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 ... WebOct 19, 2015 · Re: Determining which elements are octet exceptions. Postby Rex Lee 1C » Fri Oct 16, 2015 11:08 pm. Octet exceptions occur because of the use of electrons in d orbitals. Therefore, elements with access to d orbitals can be exceptions to the octet rule. Most commonly, this includes elements like Phosphorus and Sulfur. WebFluorine is a second period element which can only contain a maximum of 8 valence electrons. Xenon meanwhile can have an expanded octet and can hold more than 8 … iphone dcim folder naming convention
