Verified step by step guidance1
Identify the atomic number of bromine (Br) from the periodic table. The atomic number represents the number of protons in the nucleus of an atom.
Recall that a neutral atom has an equal number of protons and electrons to balance the charge.
Look up bromine's atomic number, which is 35. This means bromine has 35 protons.
Since the atom is neutral, the number of electrons must also be 35 to balance the positive charge of the protons.
Therefore, the number of electrons in a neutral bromine atom is equal to its atomic number, which is 35.
