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.
The octet rule indicates that?
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.
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.
Which doesn't violate the octet rule sf4 krf2 cf4 xef4 icl4-?
CF4 Doesn't violate the Octet Rule, the rest do.
No2 violate octet rule?
Yes
What is the Lewis formula for the octet rule for the ions ClO2?
There is ClO2 and ClO2^-. For the chlorite anion (ClO2^-) the Cl will have 10 electrons and will violate the octet rule. For ClO2, all elements will have 8 electrons.
Does BeH2 violate the octet rule?
The octet rule only applies to elements that are heavy enough to have reached the second shell of electrons. In the first shell, the octet rule does not apply because the first shell is completed with only two electrons, not eight. So no, the octet rule does not apply to beryllium hydride.
Do Cu plus and Cu2 plus plus violate the octet rule?
The octet rule does not apply to transition metals.
Octet rule for diatomic elements?
yes!
What molecules does not violate the octet rule no bcl3 bef2 sef6 f2ccf2?
F2ccf2
What is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
What molecules do not violate the octet rule?
I think two elements that does not follow the octet rule are boron and beryllium. These elements always have one electron pair less than normal configuration. Boron is an important element for our body.
What is the octet rulewhich element is the exception?
Some elements that are known to violate the octet rule are: Hydrogen, Helium and Lithium (two electrons) Aluminum and Boron (less than octet but will form an octet if possible), Period 3 elements with p orbitals (more than an octet using empty d orbitals), noble gas compounds (more than an octet), and elements like nitrogen with an odd number of electrons (form free radicals when octets are not possible).
What elements can violate the octet rule?
It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell. It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell.
How do metals obey the Lewis octet rule?
The elements can be described by dot structure. Metals combine with other elements to make its octet complete.
