Give the nuclear symbol (isotope symbol) for the isotope of bromine, br, that contains 46 neutrons per atom.

The number of protons that Bromine (Br) has = 35
The mass number of Bromine (Br) is = 35 +46 = 81
Then we can write the nuclear symbol or isotope symbol of Bromine (Br) as (superscript 81)(subscript 35)Br. I hope that this answer is the one you were looking for and it has come to your help.

It will fall off and tip over.
