Atoms of the same element with different numbers of neutrons are called isotopes Isotopes are distinguished from each other by including the mass number with the name or symbol Ions As we have seen in a neutral atom the number of protons and the number of electrons is equal Atoms can gain or lose electrons to become ions Mar 13 2023 nbsp 0183 32 Many elements are composed of a mixture of isotopes atoms of the same element with different masses Some atoms of two different elements may have virtually the same mass these are called isobars Atoms can be split fission or merged fusion in nuclear reactions
