The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons
What else can I help you with?
Which is not an octet rule?
There are several - the most notable being H+, H-, and Li+.
Give example of octet rule?
Az important rule: any octet has to have eight parts, otherwise it is not an octet.
In which bonding patterns does X obey the octet rule?
no it does not follow octet rule
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.
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 is significant of octet rule?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
What rule do the nonmetal atoms follow?
octet rule
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.
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.
