If octet rule is outdated and if certain elements become stable forming 5 bonds(PCl5) ,and what we use in organic chemistry also is octet rule only! So does this mean what we are studying is wrong? Do all atoms does not want nearest noble gas configuration then?
Answers
Answer:
Octet rule – it states that atoms of elements are stable with 8 electrons in their outermost shell and they tend to undergo chemical changes to get this structure.
Elements after these chemical changes attain noble gas configuration. Chemically active elements don’t have 8 electrons in their outermost shell and that’s why they lose or gain electrons to obtain stable octet structure.
Atoms having more than 4 electrons and less than 8 electrons, already in their outermost shell, tend to gain electrons thereby becoming negatively charged (anions). Atoms having less than 4 electrons and more than 0 electrons, already in their outermost shell, tend to lose electrons thereby becoming positively charged cations. The ultimate result of this is obtaining octet in outer most shell.
