Question

what are the three types of isotopes? list some properties of isotopes​

Answer 1

Answer:

Isotopes of the same element have different physical properties (melting points, boiling points) and the nuclei of some isotopes are unstable and radioactive.

Explanation:

Answer 2

Answer:

Isotope:  one of two or more atoms having the same atomic number but differing in atomic weight and mass number. The nuclei of isotopes contain identical numbers of protons, equal to the atomic number of the atom, and thus represent the same chemical element, but do not have the same number of neutrons. Thus isotopes of a given element have identical chemical properties but slightly different physical properties and very different half-lives, if they are radioactive.
