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.

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 the element sulfur in SO3 violate the octet rule?

Yes, the element sulfur in SO3 violates the octet rule because it has more than 8 electrons in its valence shell.


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.


How does oxygen not follow the octet rule?

Oxygen can violate the octet rule because it can form stable compounds with less than eight electrons in its valence shell. For example, in molecules like hydrogen peroxide or ozone, oxygen can have six electrons in its valence shell. This is possible due to oxygen's ability to form multiple bonds and accommodate more than eight electrons in its valence shell.

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.

Which statements about the octet rule is are true?

The bolded statements are true:1. The octet rule can be violated. 2. Atoms are most stable when their atomic number is divisible by 8.3. All free atoms contribute eight valence electrons to form molecules.4. Only the oxygen atom can have an expandable octet.5. In order to obey the octet rule, some atoms have to share more than one pair of electrons.


No2 violate octet rule?

Nitrogen dioxide (NO2) violates the octet rule because nitrogen has one unpaired electron, giving it a total of 7 valence electrons in its outer shell. This results in NO2 having an odd number of electrons, making it impossible for nitrogen to achieve a full octet.


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.


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 the statement that when atoms combine to form molecules they general lose or gain or sharevalence electrons until they attain or share eight?

This statement is known as the octet rule. It states that atoms tend to combine in such a way that they either gain, lose, or share electrons to achieve a full outer shell of eight electrons (octet) to attain stability.
