Science Buddies: "Ask an Expert"

i mostly understand that isotopes are different from atoms because the have a different amount of neutrons, but my question is why the have a different amount of neutrons and how this happens. please keep it as simple as possible please!

Hi Dani3333,
Isotopes can occur naturally or they can be produced. Please take a look at this https://www.isotopes.gov/sites/production.html

Please use the search term "Isotope production" in google for more information on the subject.

Good Luck and please let us know if there's anything else we can do to help.
