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)

Step 3:
: Determine the nuclear symbol for the desired isotope

To find the nuclear symbol for the isotope with 46 neutrons, we need to subtract the atomic number (35) from the total number of nucleons (protons + neutrons) in the nucleus. Total number of nucleons = Atomic number + Number of neutrons Total number of nucleons = 35 + 46 = 81 Now, we can write the nuclear symbol for this isotope as: ^{81}_{35}\text{Br}

Final Answer

The nuclear symbol for the isotope of bromine with 46 neutrons is ^{81}_{35}\text{Br}.
