Step 1: Identify the number of protons in the element bromine
Bromine (Br) has an atomic number of 35, which is the number of protons in its nucleus. (Step 1: Atomic number of bromine = 35)
Step 2: Determine the number of electrons in the neutral atom
In a neutral atom, the number of electrons is equal to the number of protons. Therefore, a neutral bromine atom also has 35 electrons. (Step 2: Number of electrons in neutral bromine atom = 35)
Final Answer
The nuclear symbol for the isotope of bromine with 46 neutrons is ^{81}_{35}\text{Br}.
