Vedclass · Answer

(B) The atomic number $(Z)$ of bromine is $35$. The two isotopes of bromine are $_{35}Br^{79}$ and $_{35}Br^{81}$.The number of neutrons is calculated using the formula: $	ext{Neutrons} = 	ext{Mass number} (A) - 	ext{Atomic number} (Z)$.For the first isotope $(_{35}Br^{79})$: $	ext{Neutrons} = 79 - 35 = 44$.For the second isotope $(_{35}Br^{81})$: $	ext{Neutrons} = 81 - 35 = 46$.Thus,the correct number of neutrons is $44$ and $46$.

The atomic number of bromine is $35$ and its atomic weight is $79$. Two isotopes of bromine are present in equal amounts. Which of the following statements represents the correct number of neutrons?
