The octet rule in the study of chemistry states that atoms combine in such a way as they each have eight electrons in their valance. The electrons shared by two atoms in a covalent bond are counted twice.

What is octet rule and give two examples which do not follow this rule?

The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule


What do you mean by octet and duplet?

In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.


Give example of octet rule?

Az important rule: any octet has to have eight parts, otherwise it is not an octet.


Who is the inorganic chemistry?

Inorganic chemistry study compounds which not contain carbon (several exceptions to this rule exist).


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.


Is NH3 an exception to the octet rule?

NH3 is not an exception to the octet rule. Nitrogen (N) in NH3 has a total of 8 valence electrons (5 from nitrogen and 3 from hydrogen), fulfilling the octet rule. Nitrogen has 3 bonded pairs and 1 lone pair of electrons, following the octet rule.


Which of the atoms don't always obey the octet rule H O Br?

Hydrogen is the atom that doesn't always obey the octet rule. It only needs 2 electrons to have a full outer shell, rather than the 8 electrons typically required by the octet rule. Oxygen and bromine usually follow the octet rule.


Can iodine exceed the octet rule and have an expanded octet?

Yes, iodine can exceed the octet rule and have an expanded octet due to its ability to accommodate more than eight electrons in its valence shell.


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.


What is significant of octet rule?

The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
