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

The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a full set of eight valence electrons in their outermost electron shell, which is the most stable configuration. This rule helps predict how atoms will form chemical bonds with each other to achieve a more stable electron configuration.

∙ 14y agoElements in Groups 1-7A (1,2,13-17) react with other elements by forming ionic or covalent bonds to produce a noble gas configuration, usually 8 electrons in the outter shell.
There are two exceptions to the rule: Hydrogen and Helium.

∙ 15y agoall the atoms tend to complete 8 electrons in their outermost shell eitherby gaining ore losing of electrons or by sharing of electrons, this is the octet rule.

Why does sodium form chemical bond with chlorine?
Na is a e' donner atom and Cl take this e' and both complit ur octate.........
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.
What changes while the number of protons stays the same?
In an atom The number of proton and electron are same that's why the atom is electrically neutral if it completes its octate then it becomes noble configuration or neutral metal
What happen to atoms in a substance when a chemical change occur?
Then tend to become stable i.e attain an octate or duplet electron configuration.In order to do so, they form molecules by undergoing either of the 2 bondings.
Which rule is violated in the configuration of 1s2 2s2 2px2?
The rule that is violated in the configuration of 1s2 2s2 2px2 is the Hund's Rule. Hund's rule states that all electrons do not want to be with each other.
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

In an atom The number of proton and electron are same that's why the atom is electrically neutral if it completes its octate then it becomes noble configuration or neutral metal
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
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
