Respuesta :
The octet rule signifies towards the capability of the atoms to prefer to exhibit eight electrons in the valence shell. In case, when the atoms possess lesser than eight electrons, they seem to react and produce more stable components. While discussing octet rule, one does not consider d or f electrons.
According to the octet rule, the atoms of the prime-group elements seem to bind in such a manner that each atom exhibit eight electrons in its valence shell, providing it the similar electronic configuration as a noble gas.
In the given question, in BrF3, fluorine follows octet rule, while bromine does not follow the octet rule.
Answer:
BrF₃
Explanation:
Octet rule -
Octet rules determines the stability of an atom , depending on the number and arrangement of atoms .
The atoms with eight electrons are considered to be following the octet rule , are are stable .
The atoms with atoms less than or more than 8 are considered to be unstable and violating the octet rule .
from the given options in the question , BrF₃ violates the octet rule , as it has only 6 electrons .
