when forming bond why do some atoms follow and some atoms [cations(d block )] don't follow octet rule and why does the formal charge should be lowered?
PhysicoRaj said:Because atoms form bonds in order to get stable, i.e., attain the nearest noble gas configuration
abi.ayan said:why does noble gas configuration stable than other configurations?
The octet rule is a chemical principle that states atoms tend to gain, lose, or share electrons in order to obtain a complete outermost energy level with 8 electrons, similar to the noble gas configuration. This gives the atom greater stability and makes it less reactive.
Atoms follow the octet rule because it allows them to achieve a more stable electron configuration. By having a full outermost energy level, atoms have a lower energy state and are less likely to react with other atoms.
Yes, there are some exceptions to the octet rule. Atoms with fewer than 8 electrons in their outermost energy level, such as hydrogen and helium, only require 2 electrons to achieve stability. Additionally, elements in the third period or higher on the periodic table can exceed the octet rule due to the presence of d orbitals.
The octet rule plays a major role in chemical bonding. Atoms will gain, lose, or share electrons in order to achieve a full outermost energy level, resulting in the formation of ionic or covalent bonds. This allows atoms to become more stable and form compounds with other elements.
If an atom cannot follow the octet rule, it may form unstable compounds or react with other atoms to achieve a more stable electron configuration. Alternatively, the atom may undergo hybridization, where orbitals are combined to form new hybrid orbitals that allow for the bonding of atoms in a different way.
