Isotopes are atoms of the same element with different numbers of neutronsatoms are 3 types of subatomic particles; electrons, protons and neutronsatomic number is the number of protons and a characteristic for the item. the mass number is the sum of protons and neutrons. Isotopes are atoms of the same element, so the number of protons are the same, but the neutrons are different so the mass number is changecorrect answer is 1⁴₇N and 1⁸₇N . subscript is the atomic number - 7 therefore, both are the same element - Nsuperscript is the mass number , 14 and 18 are different. Therefore, these 2 are isotopes.
