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.
Elements with more than eight valence electrons (expanded octet) or less than eight valence electrons (incomplete octet) can violate the octet rule. Examples include elements in the third period or below in the Periodic Table such as phosphorus, sulfur, and chlorine. Additionally, transition metals and elements with vacant d orbitals can also violate the octet rule.
Potentially elements above neon in the periodic table, as these have d orbitals and te hevier ones f orbitals . In practise exclude the group 1,2 elements. The "expansion" of the octet is common it is a rule but in inorganic chemistry all rules are made to be broken even this one. P.S don't forget Hydrogen that obeys the duet rule (Helium configuration)!
when the central atom has more than 8 electrons,it is octet rule violation

Which doesn't violate the octet rule sf4 krf2 cf4 xef4 icl4-?
CF4 and XeF4 do not violate the octet rule. In CF4, carbon forms four covalent bonds with fluorine, fulfilling the octet rule. In XeF4, xenon forms four covalent bonds with fluorine and has two lone pairs, also satisfying the octet rule.
Do Cu plus and Cu2 plus plus violate the octet rule?
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of 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.
What molecules do not violate the octet rule?
Molecules that do not violate the octet rule include hydrogen (H2), beryllium (BeCl2), and boron (BCl3). These molecules satisfy the octet rule by having less than eight electrons around the central atom.
What is the Lewis formula for the octet rule for the ions ClO2?
The Lewis formula for the ion ClO2 is O=Cl=O with one lone pair on each oxygen atom. Each atom satisfies the octet rule, with the chlorine atom having 6 valence 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.

What is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence 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.
What is the Lewis formula for the octet rule for the ions ClO2?
The Lewis formula for the ion ClO2 is O=Cl=O with one lone pair on each oxygen atom. Each atom satisfies the octet rule, with the chlorine atom having 6 valence electrons.
Which rule says that elements will bond to a total number of 8 electrons to be stable?
octet rule
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).
Which statements about the octet rule is are true?
The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons. The octet rule is observed in many covalent and ionic compounds. Atoms can sometimes violate the octet rule, particularly when dealing with elements that can accommodate more than 8 electrons in their valence shell.
