The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
An element will be stable once it has 8 valence electrons
What else can I help you with?
What are the limitations and disadvantages of ionic bonding?
Ionic bonding can lead to brittle compounds due to the rigid arrangement of ions in the crystal lattice. The strength of ionic bonds can weaken in the presence of water or other polar solvents, affecting the stability of the compound. In some cases, the transfer of electrons in ionic bonding can lead to the formation of highly reactive species.
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 rule is violated in the configuration of 1s2 2s2 2px2?
Hund's rule is violated in this configuration. According to Hund's rule, electrons will fill empty orbitals before pairing up in the same orbital. In this case, the electrons should have filled the 2py and 2pz orbitals first before pairing up in the 2px orbital.
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.
What is the key difference between the Zaitsev and Hofmann rule in organic chemistry?
The key difference between the Zaitsev and Hofmann rule in organic chemistry is that the Zaitsev rule states that the major product of a reaction is the more substituted alkene, while the Hofmann rule states that the major product is the less substituted alkene.
If DHCP server uses the subnetmask 225.225.225.0 how many ip address can it produce?
Hi Friend, i Think that there is a problem in question or i am not aware about it, becoz first octate should fill first so it would be 255.255.225.0, when 2 octate will full then u can reach on third octate. if we leave first octate on 225, it means it doesn't cover all ip of A class, so it can't move further. if there is any update, then plz mail me @ mohitdns@AOL.in Thanks Mohit Sharma
What is valance electron and free electrol describe with figure?
valence electrons are the remaining electrons after which an atom has attains its octate level
How many electrons do hydrogen gains or lost?
Hydrogen shares its electrons to complete the octate so it gains 1 electrons. it can also its electrons.

Explain the Net id and Host id of 114.34.2.8?
First octate i.e. 114 indicates that its a A class network.In case of 114.34.2.8 the net id is 114 and the host id is 34.2.8
The summary of the poem 'sonnets to the pupils of Hindu college' by derozio?
ans.4 yes sonnet are type of poem consitisting of 14 lines first 8 octate and other 6 sestet
How many electrons are total in the levels of a stable atom?
Well it depends upon which element you are talking about Eg flourine atom has 9 protons and electrons normally configuration will be 2,8,1 But if u r talking about a stable fluorine electron, configuration will be 2,8 This happens since the outermost octate of fluorine is not filled completely so it is not stable in it's structure so it loses the 1 extra electron in it's last octate and becomes stable gaining a negative charge Ultimately no. Of levels vary from element to element
What is octate state?
The octet state refers to a configuration in which an atom has eight electrons in its outermost shell, achieving a stable electron arrangement similar to that of noble gases. This concept is central to the octet rule in chemistry, which states that atoms tend to bond in ways that allow them to have eight valence electrons. Atoms often achieve this stability through the formation of covalent or ionic bonds. The octet state is crucial for understanding chemical reactivity and the formation of molecules.
How are molecules of an element and a compound different?
Hydrogen symbol : H , and atomic number : 1 is an element . Whereas H2 is the hydrogen compound . The element may not be stable but molecule are always stable . When we see the molecular structure of hydrogen element , the outer most valence shell has one electron , which means hydrogen needs one more electron to fulfill its duplet . When the octate and duplet are fulfilled they are stable . In compound various element and molecules , bond to complete each others octate or duplet . Compound have certain bond . Eg electrovalent bond and covalent bond .
How do element become stable?
The elements can only be stable when it complete is octate in its outer most orbit has 8 electrons in its outer most orbit by gaining or losing energy
In mathematics the rule is l-hospetal rule or lhospetal rule?
L'Hôpital's Rule or L'Hôspital's Rule
Who said rule by few rule by one rule by many?
Aristotle came up with the rule by few, rule by one, and the rule by many.
