Unfortunately, there is no chemical substance with the formula BrF13 that exists in reality.
Bromine (Br) can only form compounds with Fluorine (F) with the formula BrF, BrF3, and BrF5. These compounds are formed because bromine has a valency from 1 to 7 and fluorine only has a valency of 1.
We can’t make a BrF13 compound because bromine can’t make 13 bonds at once with fluorine due to the limitation of the number of electrons in bromine’s outermost shell.
According to the octet rule, an atom will have its most stable chemical nature when it has 8 electrons in its outer shell. Bromine already has 7 electrons in its outer shell, so it can only accept a maximum of 1 more electron to achieve a stable nature, and therefore can’t make 13 bonds at once.
We apologize for the confusion, but we cannot provide detailed information about a substance that doesn’t exist.
