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 else can I help you with?
Which molecule obeys the octet rule cl3cf bcl3 no sbf5 beh2?
BCl3 and BEH2 obey the octet rule because Boron and Beryllium are exceptions to the octet rule and can have stable electron configurations with less than 8 electrons. Cl3CF, NO, and SbF5 do not obey the octet rule because they have incomplete or expanded valence shells.
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.
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.

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.

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.
Why BeH2 and SF6 disobey octet rule?
Sulfur is in period 3 and has 6 valence electrons. The expected fluoride would be SF2, SF^ a very stable compound is surprisoing. The bonding in SF6 has been described in a number of ways- one is that there is sp3d2 hybridisation and there are 6 equivalent 2 electron 2 center bonds. Other descriptions involve resonance of ionic canonicals where the octet is preserved. Yet another description is "hypervalency" involving 3 centre bonds. With BeH2 the situation is different, in this there are not enough electrons to form an octet. Some call this electron deficiency. In BeH2 each Be is surrounded by 4 hydrogen atoms, and there 4 BeHBe bonds- 3 center 2 electron. These are similar to bonds in B2H6. The octet rule is a guideline- it has proved to be remarkably useful- but as someone said ".. in inorganic chemistry the rule is that there are no rules"
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.
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.
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.
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
