Isotopes :- Atoms of the same element having same atomic number but different mass numbers are known as isotopes Isotopes have same number of protons but different number of neutrons in their nucleus Given atom is 79Br We need to find isotope of 79Br Given species are A) 40Ar+ Incorrect , Isotopes are atoms of same element , Ar can't be an isotope of Br because it is atom of different element B) 79Se Incorrect , Isotopes are atoms of same element , Se can't be an isotope of Br because it is atom of different element C) 79Br- Incorrect , Isotopes have different mass numbers Mass numbers of both species 79Br and 79Br- are same , hence they are not isotopes D) 80Br Correct , 80Br and 79Br are atoms of same element with different mass numbers. Therefore they are isotopes E) 34S2- Incorrect , Isotopes are atoms of same element , S can't be an isotope of Br because it is atom of different element Answer :- D) 80Br
