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.

Which molecule obeys the octet rule cl3cf bcl3 no sbf5 beh2?
Cl3CF
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
Do Cu plus and Cu2 plus plus violate the octet rule?
The octet rule does not apply to transition metals.
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.

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.

F2ccf2

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"
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.
How does oxygen not follow the octet rule?
It does follow the octet rule!
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
Is NH3 an exception to the octet rule?
No, CH4 follows the octet rule.
