WebThe octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. WebAug 5, 2024 · The 'octet' rule is based upon available n s and n p orbitals for valence electrons (2 electrons in the s orbitals, and 6 in the p orbitals). Beginning with the n=3 principle quantum number, the d orbitals become available ( l =2). The orbital diagram for the valence shell of phosphorous is:
The Octet Rule Explanation in Chemistry - ThoughtCo
WebWhile most atoms obey the duet and octet rules, there are some exceptions. ... many elements in the third-row and beyond have been observed to exceed the octet rule, forming compounds in which the central atom is surrounded by more than eight electrons (e.g. ICl₄⁻ or PF₅). ... Another boron compound is borane (BH3) which is where a boron ... WebJul 27, 2024 · BF 3 follows the octet rule because the Boron has three electrons so that it can give one electron to each of the three fluorine atoms. this gives each of the florine ions eight electrons. The Boron ends up with no electrons in the outer shell, The complete inner shell is the same as group VIIIA helium. hobby cabinet lighting
Why BH3 obey the octet rule? - Answers
WebJul 3, 2024 · The octet rule states that elements gain or lose electrons to attain an electron configuration of the nearest noble gas. Here is an explanation of how this works and why elements follow the octet rule. The Octet Rule Noble gases have complete outer electron shells, which make them very stable. WebThe octet rule is a general rule that only applies to main group elements (groups 1-2 & 13-18), but of course has plenty of exceptions within those groups. Most of chemistry is … WebAnswer the following questions based on the compounds BH3 and AsF4- i) Draw the Lewis structure and if octet rule is not satisfied state which type of octet rule exception is applied?
