The number of neutrons is different.
=Unlike stable isotopes such as Carbon- 12 or oxygen- 1, radioisotopes spontaneously change into other isotopes over time.=
Sodium-23 and Sodium-22 are two isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24).
Sodium does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
The number of neutrons is different.
they are different isotopes of copper 1 has 2 more neutrons than the other
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.

No, they contain different number of electrons. Isotopes differ in their number of neutrons.
Isotopes of an element have different numbers of neutrons.

No they don't have. Isotopes of an element differ in mass from from each other and this is due to the different no. of electrons in their nucleus.
They have the same formulas but different organic structures.
Sodium-23 and Sodium-22 are two common isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24). -V
A natural chemical element may be monoisotopic or has isotopes. Isotopes are atoms but they differ from other isotopes by the number of neutrons. This involve a different atomic mass and different physical properties or sometimes (for light isotopes) different chemical properties. Also, all chemical elements have radioactive, artificial isotopes.
