Phosphorous, Chlorine, and Sulfur can accommodate more than eight electrons and therefore break the octet rule because they contain a 3d orbital. Does BeCl2 follow octet rule? BeCl2 violates the octet rule because the boron should be in a suitable valence state such that it binds to 3 chlorines. See more Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell. This can only occur when the valence shell has … See more The two elements that most commonly fail to complete an octet are boron and aluminium; they both readily form compounds in which they have six valence electrons, rather than … See more Exceptions to the Octet Rule. Elements that go below the octet rule: Boron and Beryllium-These 2 elements tend to violate the octet rule by having fewer than 8 electrons around them. … This occurs because elements in … See more BCl3 do not obey octet rule.It is a electron deficient molecule.As it share only three electron with chlorine atom . After forming a molecule boron … See more 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 learning these simple rules and later discovering that actually it's a lot more complicated and full of subtle nuances.

WebAug 11, 2024 · The p- and s-block elements heed the octet rule except for helium, hydrogen, and lithium (Li). Metals such as sodium or magnesium also obey the octet rule. Some other rules, such as the duplet rule or rule of two and 18-electron rules, are followed by other elements. The duplet rule is for helium (He) and hydrogen (H), or the 18 … WebDec 9, 2024 · Which elements are we required to know that break the octet rule for this class? It is better to think of it conceptually that if an element has access to a d-orbital it … dr. nicholas richardson brunswick ga

WebGroup 17 elements have 7 valence electrons and strongly desire one more to satisfy the octet rule, going as far as to rip the electron from another neighboring atom. This is why halogens are so reactive: they … Web(Select all that apply.) Which of the following elements cannot break the octet rule by having more than 8 electrons when it is a central atom?
