Question

The tendency of atoms of elements to gain or lose electrons so that their outer s and p orbitals are filled with eight electrons is called ______ rule

Answer 1

Answer: Octet rule

Explanation: The elements which have filled s and p orbitals or noble gases are most stable and thus every element tends to get stable by completing their octet.

For example: Sodium [Na] has atomic no of 11 and thus the electronic configuration is :
`Na:1s^22s^22p^63s^1` tends to get stable by losing one electron and gets converted to
`Na^+`

Electronic configuration for
`Na^+:1s^22s^22p^6`

Thus acquiring stable configuration with filled s and p orbitals.

For example: Fluorine [F] has atomic no of 9 and thus the electronic configuration is :
`NF:1s^22s^22p^5` tends to get stable by gaining one electron and gets converted to
`F^-`

Electronic configuration for
`F^-:1s^22s^22p^6`

Thus acquiring stable configuration with filled s and p orbitals.
