  • Isotopes are the atoms of same element, they have same atomic number but different mass number. Isotopes have different number of neutrons in their nucleus. If an element exists in two isotopes having atomic masses .a. and .b. in the ratio m : n, then average atomic mass will be mxa+nxb//m+n Different isotopes of same element have same position in the periodic table. The elements which have single isotope are called monoistropic elements. Greater is the percentage composition of an isotope, more will be its abundance in nature. The isotopes of chlorine with mass number 35 and 37 exist in the ratio (if its average atomic mass is 35.5)
