what are isotopes and also examples of it
Answers
Answer:
hey mate here is your answer
Explanation:
There are 275 isotopes of the 81 stable elements. There are over 800 radioactive isotopes, some of which are natural and some synthetic. Every element on the periodic table has multiple isotope forms. The chemical properties of isotopes of a single element tend to be nearly identical. The exceptions are the isotopes of hydrogen, since the number of neutrons has such a significant effect on the size of the hydrogen nucleus. The physical properties of isotopes are different from each other since these properties often depend on mass. This difference may be used to separate isotopes of an element from each other by using fractional distillation and diffusion.

Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons).
Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope).
Uranium-235 and uranium-238 occur naturally in the Earth's crust. Both have long half-lives.
