Some isotopes are unstable Reviewing Isotopes Atoms with same number of protons but different numbers of neutrons Example: Carbon-12 (normal carbon) versus Carbon-14 Some isotopes are unstable Nuclei break down in a process of radioactive decay, releasing particles and energy Radioactivity Unstable nu...
atoms of the same element w/different #s of neutrons are called isotopes. in order to know how many neutrons in an atom you must be told. the mass number tells you how much mass t 13、he atom has. since p+ and n0 are the heavy parts, mass # = # of p+s + n0s.question: if...
