In chemistry, the octet rule states that an atom has eight electrons in its outer shell. When all eight electron orbitals are filled, the atom is described as non-reactive. Examples include neon and argon.

∙ 14y agoThe octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons

Which three elements violate the octet rule?
The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.
How does an atom of boron become stable?
In general, boron will form 3 covalent bonds, using each of its 3 valence shell electrons (sharing them). This will of course violate the octet rule, but obeys the sextet rule, and this is what makes boron stable. It (along with aluminum, eg.) do not obey the octet rule.
The octet rule states that chemical compounds tend to form so that each atom has an octet of electrons in?
The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.
How will an atom react if the octet rule is or is not satisfied?
Yes, for example, BF3. Boron will still bond with other things even though it had 6 electrons
Why is the molecule SF4 an exception to the octet rule?
The molecule SF4 doesn't have eight electrons like most atoms, it can expand the octet because sulfur has 6 valence electrons and each fluorine only needs one electron to share with sulfur so that leaves to remainder.
How does oxygen not follow the octet rule?
It does follow the octet rule!
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
Is NH3 an exception to the octet rule?
No, CH4 follows the octet rule.
What are 3 atoms are exceptions to the octet rule?
Boron is one. It exceeds the octet rule.
In which bonding patterns does X obey the octet rule?
no it does not follow octet rule
Will any of the chlorine oxides obey the octet rule?
No chlorine oxides will obey the octet rule.
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
Do Cu plus and Cu2 plus plus violate the octet rule?
The octet rule does not apply to transition metals.
What is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
Which of the atoms don't always obey the octet rule H O Br?
Chlorine Cl : it can have a higher valence (ClO2, HClO3) than predicted by the octet rule. Hydrogen H and oxygen O cannot escape the octet rule.
What rule do the nonmetal atoms follow?
octet rule
Does PCl2F3 follow the octet rule?
yes PCl3 obey octet rule there are 5 electrons in the valence shell of phosphorous it need 3 electron to complete its octet so it form bond with 3 chlorine after bond formation there are 8 electron in its octet it obey octet rule
